    Abstract - (Show below) - (Hide below)

    Gives dimensions for range of nominal sizes from 12 mm (M12) to 36 mm (M36) inclusive and specifies mechanical properties. Full details of tests, inspection procedure and provisions for marking are also included. NOTE. It is important to ensure that these bolts are correctly used if satisfactory results are to be obtained. Recommendations giving guidance in the use of this form of fastener are given in BS 4604-1.
