Value Collection MP97031 Hex Head Cap Screw 5/16-18

Product Description

The VALUE COLLECTION MP97031 is a 5/16-18 x 1-1/2 inch hex head cap screw manufactured from Grade 5 steel with an uncoated finish. It features partial threading along the shank and conforms to ASME B18.2.1 dimensional standards. This fastener uses a Unified National Coarse (UNC) thread form and is measured under the head at 1-1/2 inches. It is a standard inch-system hex cap screw suited for general mechanical assembly applications across industrial, HVAC, plumbing, and equipment maintenance work. Sold in a package quantity of 50 with a minimum order quantity of 1.

This screw is commonly used in structural clamping, equipment mounting, and mechanical assembly where a partially threaded shank is required for accurate bearing and alignment. Grade 5 steel provides a reliable strength level for medium-duty fastening in both residential and light commercial applications. The uncoated finish is appropriate for dry indoor installations or where a separate coating or lubricant will be applied at the job site.
