Standard BS 4190 5

This norm gives the general dimensions and tolerances of black hexagon bolts, screws and nuts with ISO metric threads in diameters from 5 mm to 68 mm inclusive. It also specifies and addresses mechanical properties of carbon or alloy steel bolts, screws and nuts, which are to be used for special applications. Dimensional requirements are included for bolts, screws and nuts finished black all over and for those which have partially machined finishes.
