Value Collection 97111 Hex Head Cap Screw 1/2-13 X 2-3/4 in Grade 5

Product Description

The VALUE COLLECTION 97111 is a 1/2-13 x 2-3/4 inch hex head cap screw manufactured from Grade 5 steel with an uncoated finish. The fastener features partial threading along its shank and conforms to ASME B18.2.1, the standard governing the dimensional requirements for inch-series hex cap screws. The 1/2-13 designation indicates a half-inch nominal diameter with 13 threads per inch on a Unified National Coarse (UNC) thread form. This screw is suited for structural and mechanical assemblies requiring a reliable, torqueable hex drive fastener. Sold in a package of 25 pieces per order.

This hex head cap screw is used in a wide range of mechanical, structural, and equipment assembly applications across the trades. The partially threaded shank provides a bearing surface that resists shear loads in bolted joints, making it appropriate for connecting steel members, mounting equipment frames, and securing flanged components. Licensed contractors, millwrights, and maintenance technicians working in HVAC equipment installation, plumbing equipment mounting, and general mechanical construction will encounter this fastener type regularly.

Compatibility

Designed as a standard inch-series hex head cap screw compatible with any 1/2-13 UNC tapped hole or mating nut conforming to Unified National Coarse thread specifications.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson using appropriately rated wrenches or sockets for the 1/2-inch hex head. Always verify the mating thread is 1/2-13 UNC before installation to avoid cross-threading. De-energize and lock out any equipment before fastening components to mechanical assemblies per applicable OSHA lockout/tagout procedures. Do not reuse fasteners that show signs of thread damage, corrosion, or deformation.
