2 Fasteners Industry Standards and Specifications Industry Standards Most industrial fasteners are covered by two basic standards: one for materials and properties; the other, for dimensions and tolerances. Specifications for materials and properties are published by the American Society for esting and Materials (ASM), although other groups such as the Society of Automotive Engineers (SAE) also publish specifications covering these requirements. Standards for dimensions and tolerances are issued by the American National Standards Institute (ANSI) in cooperation with the American Society of Mechanical Engineers (ASME) and the Industrial Fasteners Institute (IFI). Where applicable, published specifications covering a particular fastener will be referenced in the section of this booklet dealing with that fastener. When referring to standards and specifications, we will use only the well-known initials of the above societies-ansi, ASME, IFI, ASM and SAE. Standard fasteners are basic industrial fasteners - square and hex bolts, cap screws, carriage bolts, plow bolts, lag screws, studs, nuts, rivets and others - which have been standardized over the years as to type, style, usage, properties, dimensions and tolerances. hese include a vast range of sizes and types stocked by distributors and manufacturers for an almost limitless range of applications: the assembly and maintenance of vehicles, appliances, farm equipment, construction equipment, industrial and plant machinery of all kinds, furniture and toys. Wherever there s a need for holding parts together, holding them apart, holding them up, or holding them down, a standard fastener can usually be found to do the job efficiently and economically. Modern industrial fasteners are manufactured to a variety of standards covering dimensions, tolerances, materials, mechanical properties, testing procedures, etc. Basic Fastener ypes A Bolt is a device with a head on one end of a shank or body and a thread on the other end. Designed for insertion through holes in assembly parts, it is mated with a tapped nut. ension is normally induced in the bolt to compress the assembly by rotating the nut. his may also be done by rotation of the bolt head. A Screw is a headed and threaded bolt used without a nut. It is inserted into an internally tapped hole and tension is induced by rotation of the screw head. A Stud is a fastener with no head but it has threads at both ends of the shank. It, like a screw, has one end that screws into a tapped hole. A nut is used on the other end to create tension. If a stud is threaded its entire shank length and a nut used on both ends to create tension, it serves the function of a bolt and is then classified as a Stud Bolt. FASENERS PRODUC CAALOG 2009/0 49

3 FASENERS ERMINOLOGY AND MEASUREMENS BASIC FASENER DAA SYLES OF HEAD Round Round Countersunk (button) Square Hex Standard hex bolt with hex nut he diameter of all bolts is measured as the outside of major diameter of the thread. he length of a headed bolt is measured from the largest diameter of the bearing surface of the head to the extreme end of the point in a line parallel to the axis of the bolt. For example, square or hex head bolts are measured from under the head to the end of the bolt; a bolt with a countersunk head is measured overall. he point of a bolt is always included in the measured length. Headless fasteners such as studs are measured overall, including points, except for continuousthread alloy studs made to ASM Specification A9. his type is measured from first thread to first thread. Bolts have various styles of heads. Some of the more popular styles are illustrated above. HEAVY HEADS AND NUS Bolt users may require a bolt head or nut of greater width to compensate for wide clearance in bolt holes or unusually heavy loading. For such needs we offer heavy bolt heads and nut sizes. Heavy nuts are quite common and readily available in various types and sizes but heavy head bolts have more limited availability. BOL AND NU BEARING SURFACES Cold-upset bolts made on a boltmaker usually are washer faced but large or very long bolts may have a flat face (not machined). Nuts made on cold nut-formers may have double chamfered or washer faces. Large size nuts have hot-forged washer bearing faces, not machined, unless specially ordered. 0

4 Fasteners HEA REAMEN Heat treatment covers various techniques that may be used to develop certain end-product characteristics. Customary procedures for fasteners include annealing, stress relieving, case hardening, direct quench and temper, and carbon restoration. ANNEALING A thermal cycle involving heating to, and holding at a suitable temperature and then cooling at a suitable rate, for such purposes as reducing hardness, improving machinability, facilitating cold working, producing a desired microstructure, or obtaining desired mechanical or other properties. SRESS RELIEVING A thermal cycle involving heating to a suitable temperature, usually 000/200 F, holding long enough to reduce residual stresses from either cold deformation or thermal treatment, and then cooling slowly enough to minimize the development of new residual stresses. CASE HARDENING A term descriptive of one or more processes of hardening steel in which the outer portion, or case, is made substantially harder than the inner portion, or core. Most of the processes involve either enriching the surface layer with carbon and/or nitrogen, usually followed by quenching and tempering, or the selective hardening of the surface layer by means of flame or induction hardening. QUENCHING AND EMPERING A thermal process used to increase the hardness and strength of steel. It consists of austenitizing, then cooling at a rate sufficient to achieve partial or complete transformation to martensite. empering should follow immediately, and involves reheating to a temperature below the transformation range and then cooling at any rate desired. empering improves ductility and toughness, but reduces the quenched hardness by an amount determined by the tempering temperature used. MECHANICAL PROPERIES Standard industrial fasteners are manufactured from either carbon or alloy steels. When strength requirements are moderate, low-carbon steel is used. High-strength fasteners are made from medium-high carbon or alloy steels and are heat treated to develop desired properties. Most fasteners are covered by specifications that define required mechanical properties such as tensile strength, yield strength, proof load, and hardness. ENSILE SRENGH he maximum tensile stress in pounds per sq. in. which a material is capable of sustaining, as developed by a tension test. YIELD SRENGH he stress at which a material exhibits a specified deviation from the proportionality of stress to strain. he deviation is expressed in terms of strain, and in the offset method, usually a strain of 0.2 percent is specified. PROOF LOAD he point to which a material may be stressed without evidence of permanent deformation. HARDNESS he resistance of a material to plastic deformation. Usually measured in steels by the Brinell, Rockwell, or Vickers indentation-hardness text methods. FASENERS PRODUC CAALOG 2009/0

5 FASENERS SCREW HREADS HREAD FORMS Screw threads are spiral grooves produced on the outside of a bolt (external threads) or machined inside a nut (internal threads). Four thread forms have been established by the ANSI: UN (internal and external threads). UNR (external threads only), UNK (external threads only), UNJ (internal and external threads). CU VS. ROLLED HREADS he terms rolled thread and cut thread refer solely to the physical characteristics of commercial bolts or studs, not to the method of thread production. A cut-thread bolt has a shank diameter equal to the threaded diameter; a rolled-thread bolt has a shank diameter less than the threaded diameter. CLASSES OF HREAD FI Classes of thread fit are distinguished from each other by the amounts of tolerance specified. Classes A, 2A, and A apply to external threads; Classes B, 2B and B, to internal threads. Classes A and B are shown in ANSI standards but are rarely used. Most standard fasteners are produced with a Class 2A fit for bolts and a Class 2B fit for nuts. he Class 2A allowance assures easier assembly of mating parts, minimizes galling and seizing in high-cycle wrench assembly, and can be used to accommodate commercial electroplated finishes. Classes A and B afford no allowance or clearance for mating parts and are used chiefly for applications where a close tolerance fit is important. Class is a special interference fit which results in an actual overlap of dimensions when threaded parts are fitted together. It is normally used only on the tap-end of studs. hreading requirements are designated () by the number of threads per inch applied to a specific diameter; (2) by the initial letters of the thread standard (UNR or UN); () by the letters C, F, or numeral 8 to indicate coarse-, fine-, or 8-thread series; and (4) by the thread fit. he following example illustrates the method of designating a screw thread: /2 in. - UNRC-2A where /2 in. = nominal diameter of thread = number of threads per inch UNR = thread form standard (Unified National Radius-Root) C = coarse-thread series 2A = class of thread fit he coarse-thread series (UNRC or UNC) is used on the vast majority of bolts and nuts. Number of threads per inch ranges from 20 threads for a /4-in.- diameter bolt to 4 threads for a 4-in.-diameter bolt. he fine-thread series (UNRF or UNF) is found mostly in automotive and aeronautical work. hreads per inch range from 28 threads for a /4-in.-diameter bolt to 2 threads for a -/2-in.-diameter bolt. here is no fine-thread standard for fasteners over -/2 in. he 8-thread series (8UNR or 8UN) is used only for sizes over in. in diameter, usually in hightemperature, high pressure service. 2

7 FASENERS Description: Brass, composed nominally of Copper and Zinc, is the most common copper-base alloy. Its uses are myriad since it is relatively inexpensive, is easily worked into any shape or form and possesses strength, toughness and good corrosion resistance. Description: Silicon Bronze is the generic term used for various types of Copper- Silicon alloys. he most common of these are Everdur, Duronze, Herculoy, PMG Metal and Olympic Bronze. he properties of these trade named alloys are all basically the same with high percentages of Copper and small amounts of Silicon, Manganese or Aluminum added for strength. Lead is also added for free machining qualities where required. BRASS CHARACERISICS: Cold drawn Brass has an even greater tensile strength than mild Carbon Steel. It is both tough and malleable, qualities that make it particularly desirable for fasteners. It is immune to rust with generally high resistance to corrosion. It takes a high, lustrous finish and is non-magnetic. SILICON BRONZE CHARACERISICS: Silicon Bronze possesses high tensile strength superior to mild Steel. It has high resistance to corrosive influences such as extreme temperatures, atmospheric conditions, natural and sea water, gases and sewage. It is non-magnetic and has excellent machining and working characteristics. Uses: Fastenings made from Brass and related alloys are widely used in electrical communications equipment, builders hardware, marine hardware, a wide variety of out-of-doors assemblies, uncountable consumer, industrial and scientific products and for general use where a rustproof bolt or screw is required. Uses: Pole line hardware, switchgear equipment, sewage disposal, marine applications, water meters, valves and systems, chemical, plumbing and liquid handling equipment, food machinery, petroleum processing and all applications where exposure to the elements is a factor. Description: Stainless Steels are broadly defined as Iron alloys containing from 2 to 0% Chromium and from 0 to 20% Nickel. his analysis is further modified by additions of Carbon and other minor elements which contribute specific effects either to control mechanical properties or to improve corrosion resistance. he corrosion resistance of Stainless Steels is attributed to a surface phenomenon, passivity. When oxygen comes in contact with the surface it forms an invisible film which protects the underlying metal from rusting and corrosion under severe environment. SAINLESS SEEL CHARACERISICS: he family of Stainless Steels is divided into three general classifications: Austenitic Stainless Steels make up the general group of the 8-8 (or 00) series. hey are the Chromium-Nickel type containing upwards of 8% Nickel. hey are not hardenable by heat treatment, non-magnetic for practical purposes and offer the greatest degree of corrosion resistance. Martensitic Stainless Steels contain from 2 to 20% Chromium. hey are magnetic and hardenable. ype 40 and 46, common fastening alloys, are Martensitic Stainless Steels. Ferritic alloys are also Chromium Stainless Steel alloys. hey are magnetic and not hardenable by heat treatment. ype 40 is an example. Uses: here are almost as many uses for Stainless Steel fastenings as there are problems of corrosion, temperature and strength. Because of its high tensile strength, corrosion resistant qualities and ability to attain a mirror-like finish it is one of the most versatile of all metals. Applications include its use in the petroleum, chemical, food, plumbing, transportation and oil equipment industries to mention just a few. Listed on page 2 are the types of various Stainless Steel alloys which are most frequently used in the manufacture of fastenings. 4

As an example, M 8 x is a standard ISO Metric screw thread having a basic diameter of 8 millimeters and a thread pitch of millimeter. o convert an ISO Metric screw thread designation to a Unified (American) designation divide the basic diameter by 2.4 and multiply the reciprocal of the pitch by 2.4 to determine nominal size in inches and threads per inch. By so doing, M 8 x becomes UNS. Unified screw threads are designated by nominal size and number of threads per inch. As an example, /4-0 UNC is a standard Unified screw thread having a nominal size of /4 inches and 0 threads per inch. o convert a Unified screw thread designation to an ISO Metric screw thread designation multiply nominal size by 2.4 and multiply the reciprocal of threads per inch by 2.4 to determine basic diameter in millimeters and pitch in millimeters. By so doing, /4-0 UNC converted to ISO Metric becomes M 9.0 x 2.4. FASENERS PRODUC CAALOG 2009/0
