This British Standard 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. Mechanical properties are included for steel bolts, screws and ordinary plain nuts, which may be produced by hot or cold forging at the option of the manufacturer.
Metric DIN 931 Hexagon Head Cap Screws/Bolts are externally threaded fasteners with a hexagonal washer faced head and a chamfered tip to facilitate mating with an internally threaded component. DIN 931 hex screws have a partially threaded shank and are manufactured to very strict tolerances.
This document specifies the characteristics of hexagon head bolts, in steel and stainless steel, with metric coarse pitch threads M1,6 to M64, and with product grades A and B. If in certain cases other specifications are requested, property classes and stainless steel grades can be
Fasteners — Hexagon head screws — Product grades A and B 1 Scope This International Standard specifies the characteristics of hexagon head screws with threads from M1,6 up to and including M64, of product grade A for threads M1,6 to M24 and nominal lengths up to
Grade 7L. Compatible denotes commercially available nut having suitable mechanical properties and dimensional configuration or style which will make it possible to obtain the desired bolt load. Higher strength nuts or nuts of equal strength may be a suitable substitute provided bolt standard allows.
