Value Collection 403118PR Hex Head Cap Screw 3/8-16

Product Description

The VALUE COLLECTION 403118PR is a 3/8-16 x 2-1/2 inch partially threaded hex head cap screw manufactured from Grade 2 steel with a zinc-plated finish. The partial threading is suited for clamping applications where the shank provides a smooth bearing surface between fastened components. The zinc plating offers basic corrosion resistance for general-purpose indoor and light-duty outdoor installations. This fastener follows Unified National Coarse (UNC) thread standards and accepts a 9/16-inch hex wrench or socket. Plumbers, electricians, HVAC technicians, and general contractors reach for this screw when assembling brackets, equipment frames, and mechanical supports.

This screw is a standard inch-system fastener intended for a wide range of light-to-moderate load applications in residential and commercial construction and equipment assembly. Common uses include mounting structural brackets, equipment supports, junction box assemblies, and general mechanical connections where a Grade 2 steel fastener meets the load and environmental requirements of the job.
