Can only be supplied if the quantity required is sufficient to warrant manufacture. IMPORTANT NOTE It is a requirement of BS EN that The bolt, nut and washer assembly is supplied by one manufacturer who is responsible for the function of the assembly. All the components are identified with the manufacturer s mark. The coating of the assembly is under the control of the manufacturer. Cooper & Turner BS EN HR preload assemblies are supplied in accordance with k class K0 this means that C&T EN preload assemblies should only be installed using Direct Tension Indicators (DTI s). CE marking can only be supplied if the whole assembly (bolt, nut, washer(s) and DTI) is purchased. Dimensions are in millimetres and apply prior to any coating.
