Value Collection 30111 Hex Cap Screw 1/2-13 X 2-3/4 in Grade 5 25pk

Product Description

The VALUE COLLECTION 30111 is a 1/2-13 UNC hex head cap screw manufactured from Grade 5 steel with a zinc-plated finish. At 2-3/4 inches in length under the head and partially threaded, this fastener meets ASME B18.2.1 dimensional standards. It is suited for general mechanical assembly, structural connections, and equipment maintenance across HVAC, plumbing, electrical, and industrial trade applications. Licensed tradespeople and maintenance professionals rely on this screw for reliable clamping force in mid-duty fastening tasks where a standard hex drive and controlled thread engagement are required.

This screw is appropriate for use in residential and light commercial equipment assemblies, panel mounting, bracket attachment, and field repairs. The 1/2-13 UNC thread pitch is one of the most common inch-series thread standards, making this fastener widely compatible with standard hex nuts, locknuts, and threaded inserts found throughout trade equipment. The partial threading provides a smooth shank section that helps align mating components before thread engagement. Sold in a package quantity of 25 units, making it practical for service vehicles and shop inventory.
