Value Collection CER88412639 Hex Cap Screw 1/4-20 316 Ss

Product Description

The VALUE COLLECTION CER88412639 is a 1/4-20 UNC hex head cap screw designed for fastening applications that demand corrosion resistance. Manufactured from Grade 316 stainless steel with a bright, uncoated finish, this fastener measures 2-1/4 inches under the head and is partially threaded. Grade 316 stainless provides superior resistance to chlorides and marine environments compared to 304 series, making it a reliable choice in wet, chemical-exposure, or outdoor installations. Plumbers, pipefitters, HVAC installers, and mechanical contractors use this type of fastener when stainless hardware is specified for equipment mounts, brackets, or structural connections.

This screw is suited for residential and commercial trade applications where corrosion-resistant hardware is required. Typical uses include equipment mounting in mechanical rooms, pool equipment installations, coastal or marine environments, and anywhere chloride exposure makes carbon steel fasteners unsuitable. The 1/4-20 UNC thread standard ensures broad compatibility with standard nuts, inserts, and tapped holes using the inch measurement system. This screw is sold individually with a minimum order quantity of 10 pieces.

Key Features

• Grade 316 stainless steel construction for high corrosion resistance including chloride and marine environments
• 1/4-20 UNC thread standard for compatibility with standard inch-system hardware
• Partially threaded shank for strong clamping force in through-bolt and bracketed applications
• Bright, uncoated finish with no added coatings or platings that could affect dimensional tolerances
• Length under head of 2-1/4 inches suits medium-depth fastening applications
• Lightweight at 0.035 pounds per fastener

Compatibility

Designed as a standard 1/4-20 UNC inch-series hex head cap screw compatible with any application requiring Grade 316 stainless steel fasteners with a partially threaded shank and 2-1/4-inch length under head.

Installation Notes

Installation is performed with a standard hex wrench or socket drive sized for a 1/4-inch hex head fastener. Always de-energize or shut down equipment before fastening or removing hardware on energized mechanical systems. Avoid mixing stainless steel fasteners with dissimilar metals in direct contact to minimize galvanic corrosion risk. Apply an anti-seize compound appropriate for stainless steel to prevent galling during installation.
