Value Collection R57001117 Hex Cap Screw 1/4-28 X 2 in 18-8 Ss

Product Description

The VALUE COLLECTION R57001117 is a fully threaded hex head cap screw designed for secure fastening in applications where corrosion resistance is critical. It features a 1/4-28 UNF thread size, a 2-inch length under head, and is manufactured from 18-8 stainless steel with no surface coating. The fine-thread UNF pitch provides stronger thread engagement per inch compared to coarse-thread fasteners, making it well suited for metal-to-metal joints and applications subject to vibration. Technicians and tradespeople across HVAC, plumbing, and general equipment assembly rely on 18-8 stainless for its balance of strength and resistance to oxidation in damp or chemically active environments.

This screw is used in light to medium-duty mechanical assemblies where a fine-thread stainless fastener is specified. Typical applications include equipment panel mounting, pipe bracket hardware, electrical enclosure assembly, and indoor or outdoor equipment frames exposed to moisture. The uncoated finish is standard for 18-8 stainless and does not require additional treatment for most indoor service environments. This item is sold individually but carries a minimum order quantity of 100 units, making it appropriate for shop stock or repeat-service inventory.

Key Features

• 18-8 stainless steel construction provides corrosion resistance in wet and chemically active environments
• 1/4-28 UNF fine thread for higher thread engagement and vibration resistance compared to coarse thread
• Fully threaded body allows clamping along the entire 2-inch shank length
• Uncoated finish is true to the 18-8 alloy with no additional plating or treatment
• Hex head drive is compatible with standard 7/16-inch hex wrench or socket tooling
• Inch measurement system with length measured under head per standard fastener convention

Compatibility

Designed as a standard 1/4-28 UNF hex head cap screw for use wherever a 2-inch fully threaded stainless fastener of this thread class is specified in equipment assembly or service work.

Installation Notes

Installation is performed with a 7/16-inch hex wrench or socket driver. Always confirm thread compatibility with the mating nut or tapped hole before driving. Power down or de-energize any equipment before accessing fastened panels or enclosures. Avoid mixing stainless fasteners with carbon steel hardware in the same joint to prevent galvanic corrosion in high-moisture environments.
