3/8-16 UNC Socket Cap Screws, 12.9 Black Steel, 1-1/4 in, Pack of 6

3/8-16 UNC socket cap screws in 12.9 grade steel

This pack contains six black self-colour socket cap screws with a 3/8-16 UNC thread and 1-1/4 inch length. Made from 12.9 grade high-tensile steel, they are suited to machine repair, maintenance and other high-stress fastening applications where a strong, compact screw head is useful.

The cylindrical socket head and internal hex drive make these screws practical for installation where there is less clearance around the fastener head than a conventional hex bolt allows. The length is measured from the underside of the head.
