Value Collection 872257PR Hex Socket Cap Screw 3/8-16 Unc

Product Description

The VALUE COLLECTION 872257PR is a hex socket cap screw designed for secure, high-strength fastening in mechanical and structural assemblies. It features a 3/8-16 UNC thread size and a 1-1/4 inch length under head, making it suited for moderate-depth fastening applications. The screw is fully threaded and driven with a 5/16 inch hex socket, allowing for high-torque installation in confined spaces where a wrench cannot reach the fastener head. Constructed from alloy steel with a zinc-plated finish, it offers solid mechanical strength and basic corrosion resistance. Machinists, maintenance technicians, and industrial tradespeople commonly install this fastener in equipment assembly, fixture mounting, and general mechanical work.

This screw is applicable in a wide range of industrial, commercial, and light manufacturing environments. The 3/8-16 UNC coarse thread pattern seats quickly and holds well in tapped steel, aluminum, and other metals. The zinc plating provides a baseline level of corrosion protection appropriate for indoor and sheltered applications. It is sold in multiples of 100 units, which suits production-line assembly, maintenance shops, and field service kits where consistent fastener stock is needed.

Key Features

• 3/8-16 UNC coarse thread for fast engagement and reliable hold in tapped metal
• 1-1/4 inch length under head provides sufficient thread engagement for standard joint depths
• Fully threaded along the entire shank for maximum thread contact
• 5/16 inch hex socket drive allows installation in tight clearance areas
• Alloy steel construction meets ASME B18.8 and ASTM A574 fastener standards
• Zinc-plated finish for basic corrosion resistance in indoor or sheltered applications

Compatibility

Designed as a standard 3/8-16 UNC hex socket cap screw compatible with any tapped hole or threaded insert conforming to that thread specification in metal assemblies and mechanical equipment.

Installation Notes

Install with a calibrated 5/16 inch hex key or socket drive. Ensure the mating tapped hole is clean and free of debris before threading to avoid cross-threading or galling. De-energize and lock out any equipment before fastener replacement or removal on live machinery. Follow applicable ASME or facility torque specifications for 3/8-16 fasteners based on the joint material and required clamp load.
