Value Collection 403032PR Hex Head Cap Screw 1/4-20 X 2-3/4 in

Product Description

The VALUE COLLECTION 403032PR is a 1/4-20 UNC hex head cap screw designed for general-purpose fastening in mechanical, industrial, and trade applications. Measuring 2-3/4 inches under the head, this partially threaded fastener is manufactured from Grade 2 steel with a zinc-plated finish for basic corrosion resistance. The partial threading provides a smooth shank section that resists fatigue in clamped joints. A 7/16-inch hex drive accepts standard wrenches and sockets found on any service truck or job site.

This screw is suited for light- to medium-duty assemblies across HVAC equipment mounting, plumbing fixture brackets, electrical panel components, and general structural fastening where Grade 2 steel meets design requirements. It follows inch-series UNC thread standards and installs with common hand or power tools. The zinc plating provides a baseline level of corrosion protection appropriate for indoor and dry-location use.

Key Features

• 1/4-20 UNC thread for wide compatibility with standard inch-series nuts and tapped holes
• 2-3/4-inch length under head suits deeper through-hole and clearance-hole applications
• Partial threading leaves a smooth shank for precise clamping and reduced stress concentration
• Grade 2 steel construction balances adequate strength with economical cost for general fastening
• Zinc-plated finish provides basic corrosion resistance for indoor and low-moisture environments
• 7/16-inch hex drive accepts standard open-end, box, or socket wrenches

Compatibility

Designed as a standard inch-series UNC hex head cap screw compatible with any 1/4-20 tapped hole, nut, or threaded insert following ASME B18.2.1 hex cap screw standards.

Installation Notes

Install with a 7/16-inch wrench or socket driver; ensure mating threads are clean and free of debris before driving. Power down or de-energize any equipment before fastening components in electrical or control enclosures. Do not exceed the design load for Grade 2 steel in high-stress or high-vibration applications where Grade 5 or Grade 8 hardware may be required. Follow applicable mechanical codes for torque and fastener specification in structural assemblies.
