Value Collection R82222863 Hex Cap Screw 1/2-13x3 18-8 Ss

Product Description

The VALUE COLLECTION R82222863 is a 1/2-13 x 3-inch hex head cap screw manufactured from 18-8 stainless steel with no coating applied. It features a standard UNC (Unified National Coarse) thread form and is dimensioned as length under head. The 18-8 stainless steel alloy provides solid corrosion resistance suitable for general industrial, mechanical, and trade applications. This fastener meets the MS 35307-419D military standard, making it appropriate for applications where a recognized dimensional and material specification is required. Licensed tradespeople and maintenance professionals working in plumbing, HVAC, electrical, and general mechanical installations regularly use this fastener type for equipment mounting, panel attachment, and structural assembly tasks.

This hex head cap screw is suited for use in both residential and light commercial installations where a 1/2-13 UNC threaded fastener with a 3-inch grip length is specified. Its uncoated 18-8 stainless steel construction makes it a common choice in wet or corrosion-prone environments such as mechanical rooms, rooftop equipment mounts, pool equipment enclosures, and plumbing utility spaces. It is sold individually, making it practical for single-fastener replacement or small-quantity service calls.

Key Features

• 1/2-13 UNC thread size — coarse thread for reliable engagement in standard tapped holes and nuts
• 3-inch length under head — full grip length for through-bolting and deep fastening applications
• 18-8 stainless steel construction — resists rust and corrosion in wet or outdoor environments
• Uncoated finish — no plating or coating that could interfere with electrical or chemical compatibility requirements
• Meets MS 35307-419D standard — recognized military specification for dimensional and material conformance
• Sold individually — single-piece quantity for replacement or low-volume service use

Compatibility

Designed as a standard 1/2-13 UNC hex head cap screw for use wherever an 18-8 stainless steel fastener of this thread size and 3-inch length is specified per MS 35307-419D.

Installation Notes

Installation is performed by the appropriate licensed trade professional depending on the application — HVAC technicians, plumbers, electricians, and millwrights all commonly use fasteners of this type. De-energize or shut off the system before accessing any equipment panels or mounting points. Use a properly sized hex wrench or socket to avoid rounding the head. Do not mix stainless steel fasteners with dissimilar metals in environments where galvanic corrosion is a concern.
