WebThis International Standard specifies the conditions for carrying out torque/clamp force tests on threaded fasteners and related parts. It is applicable, basically, to bolts, screws, studs and nuts made of carbon steel and alloy steel, whose mechanical properties are specified in ISO 898-1, ISO 898-2 or ISO 898-6, having ISO metric threads with ... WebFeb 28, 2024 · A bolt’s function essentially boils down to applying a high enough clamp force that when external forces are applied, transverse movement and separation cannot occur. ... While most bolt torque charts use this formula, these are only estimates, and since conditions can vary in real world applications, torque charts and this formula …
