BS EN ISO 8676:2011 pdf download.Hexagon head screws with metric fine pitch thread—Product grades A and B.
BS EN ISO 8676 specifies the charactenstics of hexagon head screws with metric tine pitch thread with nominal thread diameters, d, from 8 mm to 64 mm. of product grade A for nominal thread diameters. d. from 8 mm to 24 mm and nominal lengths. I, up to and including lOd or 150 mm. whichever is the shorter, and of product grade B for nominal thread diameters, d. over 24 mm or nominal lengths. 1, over lOd or 150 mm. whichever Is the shorter.
If, in special cases, specifications other than those listed In tt’s International Standard are required, they can be selected from existing International Standards, for example 1S0724, 1S0886, 1S0898-1, 150965-1, ISO 3506-1, ISO 4753 and ISO 4759-1.
