Value Collection MP72170 Hex Socket Cap Screw 3/8-16 Unc

Product Description

The VALUE COLLECTION MP72170 is a hex socket cap screw designed for secure, high-strength fastening in mechanical, structural, and industrial assemblies. Featuring a 3/8-16 UNC thread size and a 5/16-inch hex drive, this screw is partially threaded with a 2.5-inch length under head. The alloy steel construction provides excellent tensile strength, while the black oxide finish offers mild corrosion resistance and a clean appearance. Sold in a pack of 10, this fastener meets ASME B18.3 and ASTM A574 standards. It is well suited for maintenance, repair, and fabrication work across trade and industrial settings.

This screw is used in applications requiring a recessed hex drive for flush or countersunk installations where a standard hex head is not practical. The partial threading engages clamping force across the grip length, making it appropriate for bolted joints in metal-to-metal assemblies. Typical users include mechanical contractors, millwrights, HVAC fabricators, and general tradespeople working on equipment mounting, panel fastening, and structural connections. The 10-piece pack quantity suits service calls and small-batch repair jobs.
