Value Collection MP97037 Hex Head Cap Screw 5/16-18 X 3 in

Product Description

The VALUE COLLECTION MP97037 is a 5/16-18 x 3-inch hex head cap screw manufactured from Grade 5 steel with an uncoated finish. The fastener features Unified National Coarse (UNC) threading and a partially threaded shank, conforming to ASME B18.2.1 dimensional standards. Length is measured under the head. This screw is a standard mechanical fastener used across a wide range of assembly, maintenance, and repair applications in HVAC, plumbing, electrical, and general trade work. Installation is straightforward with a standard hex wrench or socket driver.

This cap screw is suited for general-purpose fastening in both residential and light commercial settings. The 5/16-18 UNC thread pattern is one of the most common inch-series coarse thread standards, making it compatible with a broad range of pre-tapped holes and standard nuts. The partial thread design concentrates clamping force and is typically used where the shank must pass through a clearance hole before engaging a threaded surface. Sold in a package quantity of 25 units, this fastener is appropriate for stock replenishment and routine service calls.
