Value Collection R57001149 Hex Cap Screw 3/8-24 X 2 in 18-8 Ss

Product Description

The VALUE COLLECTION R57001149 is a fully threaded hex head cap screw designed for general mechanical and structural fastening applications. It features a 3/8-24 UNF (Unified National Fine) thread profile and a 2-inch length under head, giving technicians precise thread engagement and clamping force in close-tolerance assemblies. Constructed from 18-8 stainless steel with no additional coating, this fastener delivers solid corrosion resistance in wet, humid, and mildly corrosive environments. It is a practical choice for HVAC, plumbing, electrical enclosure, and general trade-service work where stainless hardware is specified.

This screw is suited for residential and light commercial maintenance, equipment assembly, and field repair scenarios where a fine-thread stainless fastener is required. The UNF thread standard provides greater thread engagement per inch compared to coarse-thread variants, making it well suited for metal-to-metal joints and vibration-prone assemblies. Installers in HVAC, plumbing, and general mechanical trades will find this size commonly called for in equipment panel attachment, bracket mounting, and fixture installation.

Key Features

• 3/8-24 UNF fine-thread profile for high thread engagement and vibration resistance
• 2-inch length under head for deeper clamping reach in standard structural joints
• Fully threaded shank maximizes usable thread length across the full fastener body
• 18-8 stainless steel construction provides corrosion resistance in damp or humid service environments
• Uncoated finish maintains consistent dimensional tolerances for precise hardware fits
• Inch measurement system for direct compatibility with standard SAE tooling and hardware

Compatibility

Designed as a standard UNF hex head cap screw compatible with any 3/8-24 threaded hole or nut in inch-measurement mechanical assemblies across HVAC, plumbing, and general trade applications.

Installation Notes

This fastener is installed by licensed technicians and qualified tradespeople using standard 9/16-inch hex tooling for 3/8-inch hex head cap screws. Always de-energize equipment and relieve any system pressure before removing or replacing fasteners on live assemblies. Do not exceed the rated torque range for 18-8 stainless steel fasteners, as over-torquing can cause galling on stainless threads — apply an appropriate anti-seize compound when threading stainless into stainless to reduce this risk. Follow applicable mechanical and building codes for the trade discipline in which this fastener is used.
