Common specifications

Key specifications

Selecting the right option

Choose the thread form first: the bolt and its nut must match in thread form, diameter and pitch. Metric sizes are the nominal diameter in millimetres; compare the pitch shown for each item with your nut. Length is measured from under the head to the end of the bolt, so choose size and length together. Strength figures are the minimum tensile strengths for the class or grade and size range in the Hobson guide, which is a head-marking table, so treat them as the class or grade minimum and not a test result for the bolt (manufacturer-stated).
