Mechanical properties of steel bolts

This table contains information on the mechanical properties of steel bolts, screws and studs.

¹⁾ For structural bolting: >M 12.
²⁾ Applies only to sizes up to 16 mm thread diameter.
³⁾ Hardness values calculated on ISO/TC 17/SC6 N 357.
⁴⁾ In a case where the yield stress, ReL cannot be determined, it is permissible to measure the stress at permanent set limit, Rp0.2.
