Value Collection R82222826 Hex Head Cap Screw 1/2-13

Product Description

The VALUE COLLECTION R82222826 is a 1/2-13 x 1-1/2 inch hex head cap screw manufactured from 18-8 stainless steel with an uncoated finish. The 1/2-13 designation indicates a 1/2-inch nominal diameter with 13 threads per inch on a Unified National Coarse (UNC) thread form. Length under head measures 1-1/2 inches. The 18-8 stainless steel construction provides corrosion resistance suitable for wet, marine, chemical-adjacent, and outdoor environments. This fastener is driven with a standard hex wrench or socket and is used by mechanical contractors, HVAC technicians, plumbers, electricians, and general tradespeople wherever a corrosion-resistant structural fastener is required.

This hex head cap screw is suited for light to medium structural and mechanical assembly applications in both residential and commercial settings. Typical uses include equipment mounting, pipe support bracketing, enclosure assembly, and mechanical component fastening where exposure to moisture or corrosive conditions makes carbon steel unsuitable. It meets multiple MS military standards, making it appropriate for applications requiring documented fastener compliance.

Key Features

• 18-8 stainless steel construction resists corrosion in wet and outdoor environments
• 1/2-13 UNC thread form for broad compatibility with standard tapped holes and nuts
• 1-1/2 inch length under head suits medium-depth clamping applications
• Uncoated finish — no plating to flake or interfere with torque-tension relationships
• Meets multiple MS military fastener standards for compliance-sensitive installations

Fits any standard 1/2-13 UNC tapped hole or hex nut.

Installation Notes

Installation is performed with a standard 3/4-inch hex wrench or socket driver. Always verify thread engagement depth and ensure the mating hole or nut is also 1/2-13 UNC before installation. When fastening into dissimilar metals such as aluminum, apply an appropriate anti-galling compound to prevent seizing, which is a known risk with stainless steel fasteners. De-energize or shut down equipment before performing any fastener work on live electrical or mechanical systems.
