Value Collection R82222414 Hex Cap Screw 1/4-28 X 7/8 in 18-8 Ss

Product Description

The VALUE COLLECTION R82222414 is a 1/4-28 UNF hex head cap screw with a length under head of 7/8 inches, manufactured from 18-8 stainless steel with an uncoated finish. The fine-thread UNF configuration provides stronger thread engagement per inch compared to coarse-thread fasteners, making this screw well suited for applications where vibration resistance and precise torque control are priorities. The 18-8 stainless steel alloy delivers solid corrosion resistance without a surface coating, keeping the fastener compatible with environments where coating adhesion or contamination is a concern. Installers in HVAC, plumbing, electrical, and general mechanical assembly will find this screw appropriate for light-duty panel, bracket, and equipment fastening tasks.

This fastener fits standard 1/4-28 threaded holes and tapped bosses in inch-measurement applications. It meets multiple military specifications, making it appropriate for aerospace, defense-adjacent, and industrial equipment maintenance or repair. Typical install scenarios include securing thin sheet-metal brackets, terminal covers, and equipment enclosures where a corrosion-resistant fastener is required. Sold individually, with a minimum order quantity of 10 units.

Installation Notes

Install using a standard hex wrench or socket sized for a 1/4-inch hex head cap screw. Power down or de-energize any equipment before fastening or removing hardware in electrical or HVAC enclosures. Do not overtighten stainless steel fasteners, as galling can occur; apply anti-seize compound when threading into stainless or aluminum tapped holes. Follow applicable equipment manufacturer torque guidance and relevant codes such as NEC or IFGC where required by application.
