This Hobson purlin hex bolt, nut and washer is M12 x 30mm, class 8.8, with a hot dip galvanised finish. It is supplied as a box of 150.

Hobson lists class 8.8 as high tensile, and its class and grade chart pairs class 8.8 with imperial grade 5 (manufacturer-stated).

The pitch shown is the coarse pitch given in the Hobson thread table (manufacturer-stated). The supplier lists metric fine pitch items as separate products and says so in the name.

Proof load and minimum tensile strength come from the Hobson head-marking guide for the class or grade and size range (manufacturer-stated).

Spanner sizes (A/F) are from the Hobson spanner selection chart (manufacturer-stated).

Key specifications

Selecting the right option

Choose the thread form first: the nut must match the bolt in thread form, diameter and pitch. Metric sizes are the nominal diameter in millimetres; compare the pitch in the table with your nut. Strength figures are the class or grade minimums from the Hobson head-marking table, so treat them as the minimum for the class or grade and not a test result for the item (manufacturer-stated).
