Value Collection 872225PR Hex Socket Cap Screw 5/16-24 Unf

Product Description

The VALUE COLLECTION 872225PR is a hex socket cap screw designed for precision fastening in mechanical assemblies where a flush or recessed head profile is required. This fully threaded fastener features a 5/16-24 UNF thread and a 1/4-inch hex drive, making it compatible with standard Allen keys and hex bit drivers. Constructed from alloy steel with a zinc-plated finish, it provides solid corrosion resistance for general industrial and mechanical applications. The 1/2-inch length under head keeps the fastener compact for use in tighter joint configurations. Installation is performed by machinists, millwrights, and mechanical contractors working to ASME B18.8 standards.

This fastener is suited for a wide range of industrial, manufacturing, and equipment-assembly applications where fine-thread UNF engagement is preferred for higher clamp load and vibration resistance. The zinc plating provides a baseline level of corrosion protection appropriate for indoor and light-duty environments. It is commonly used in machine frames, fixtures, tooling plates, and equipment housings where socket cap screws are specified. This SKU is sold as a package quantity of 1 unit, with a minimum order quantity of 100 units per order.

Key Features

• 5/16-24 UNF fully threaded profile for reliable fine-thread engagement

• Zinc-plated finish provides corrosion protection for general-duty indoor use
• 1/2-inch length under head suits compact joint and fixture applications

Compatibility

Designed as an OEM-style replacement or standard-specification hex socket cap screw for applications requiring a 5/16-24 UNF fully threaded fastener per ASME B18.8 and ASTM A574.

Installation Notes

Installation is typically performed by machinists, millwrights, or mechanical technicians. Ensure mating threads are clean and free of debris before installation. Use a calibrated torque wrench with the appropriate 1/4-inch hex bit to achieve the specified clamp load without overdriving. Follow applicable machine safety lockout/tagout procedures before disassembling or replacing fasteners in powered equipment.
