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.
