Value Collection B10042 Hex Head Cap Screw 1/4-20 X 3 in

Product Description

The VALUE COLLECTION B10042 is a fully threaded hex head cap screw designed for general fastening applications across mechanical, electrical, plumbing, and HVAC installations. Sized at 1/4-20 UNC with a 3-inch length under head, this fastener is machined from 18-8 stainless steel, providing solid corrosion resistance in wet, humid, or chemically active environments. The hex drive head accepts standard wrenches and sockets. Sold in packs of 50, the B10042 is a practical bulk option for techs and tradespeople who need reliable, corrosion-resistant fasteners on hand for field work or shop stock.

This screw is suited for residential and light commercial applications where stainless steel fasteners are required. Common install scenarios include panel mounting, equipment bracketing, ductwork support hardware, conduit strapping, and plumbing fixture attachment. The 1/4-20 UNC thread standard ensures compatibility with a wide range of tapped holes, threaded inserts, and standard hex nuts found throughout trade applications. The fully threaded shank allows maximum thread engagement across the full 3-inch grip length.

Compatibility

Designed as a standard 1/4-20 UNC hex head cap screw compatible with any application requiring a fully threaded stainless steel fastener in that thread size and length.

Installation Notes

Installation requires a standard hex wrench or socket sized for a 1/4-inch hex head cap screw. Always verify thread engagement into the mating component before applying torque to avoid cross-threading. In HVAC, plumbing, or electrical applications, ensure fastener material is appropriate for the service environment and any dissimilar-metal contact is accounted for to prevent galvanic corrosion. Refer to applicable codes such as NEC or IMC for fastener requirements in code-governed installations.
