Value Collection 837219PR Hex Socket Cap Screw 5/16-18 Unc

Product Description

The VALUE COLLECTION 837219PR is a 5/16-18 UNC hex socket cap screw designed for precision fastening in mechanical assemblies, structural connections, and equipment maintenance applications. The fastener measures 3 inches in length under the head and features a 1/4-inch hex drive, accepting a standard hex key or Allen wrench. Constructed from alloy steel with a zinc-plated finish, the 837219PR provides reliable corrosion resistance and the high tensile strength typical of alloy-grade fasteners. It is partially threaded, allowing for accurate clamping force in through-bolt and blind-hole configurations. The fastener meets ASTM B695 standards for zinc coating.

This cap screw is suited for general industrial, mechanical, and fabrication work where a recessed-drive fastener is preferred to avoid interference with surrounding components. Typical applications include machine frames, fixtures, jigs, brackets, and equipment panels in both shop and field environments. The 5/16-18 UNC thread is a widely used coarse-thread specification compatible with standard tapped holes and matching hex nuts across industrial and commercial maintenance settings. Minimum order quantity is 10 units.

Key Features

• 5/16-18 UNC coarse thread for broad compatibility with standard tapped holes
• 3-inch length under head with partial threading for controlled clamping in through-bolt applications
• 1/4-inch hex socket drive accepts standard Allen keys and hex bit drivers
• Alloy steel construction provides high tensile strength for demanding fastening applications
• Zinc-plated finish meets ASTM B695 coating standards for corrosion protection

Compatibility

Designed as a standard 5/16-18 UNC hex socket cap screw suitable for use in any application requiring a coarse-thread alloy steel fastener with a 1/4-inch hex drive in this thread and length specification.

Installation Notes

Installation is performed using a 1/4-inch hex key or hex bit driver; ensure the drive tool is fully seated before applying torque to avoid rounding the socket. Verify the mating thread condition and thread engagement depth before assembly. Clean and inspect tapped holes for damage or debris prior to installation. Follow applicable machinery or structural fastening guidelines for the specific application.
