Value Collection C703122 Hex Head Cap Screw 3/8-16 Grade 8

Product Description

The VALUE COLLECTION C703122 is a 3/8-16 hex head cap screw manufactured from Grade 8 steel with an uncoated finish. At 2-3/4 inches in length under head, this fastener features partial threading along the shank and conforms to ASME B18.2.1 dimensional standards. Grade 8 steel delivers high tensile strength suitable for demanding mechanical and structural assembly work. The UNC thread form is the standard coarse-thread configuration common across industrial and commercial equipment. This screw is appropriate for maintenance technicians, millwrights, and trade professionals who require a reliable, high-strength fastener for general mechanical assembly.

This hex head cap screw is suited for a wide range of trade applications including HVAC equipment mounting, electrical panel and enclosure assembly, plumbing fixture support structures, and general industrial maintenance. The partially threaded shank provides a bearing surface for applications where a clamp load must be distributed across unthreaded material. The 3/8-16 UNC thread size is one of the most commonly specified sizes in North American mechanical assemblies, making this fastener a practical stocking item for service vehicles and shop inventory.
