Value Collection 837199PR Hex Socket Cap Screw 5/16-18

Product Description

The VALUE COLLECTION 837199PR is a fully threaded hex socket cap screw designed for secure, high-torque fastening in mechanical, structural, and industrial assemblies. Manufactured from alloy steel with a zinc-plated finish, this fastener delivers solid tensile strength and basic corrosion resistance in typical shop and field environments. The 5/16-18 UNC thread profile and 1/4-inch hex drive allow installation with a standard hex key or allen wrench. With a 3/4-inch length under head and full threading along the shank, this cap screw seats cleanly in tapped holes and provides consistent clamping force across the joint.

This screw is suited for general-purpose fastening applications across manufacturing, maintenance, and equipment assembly. The 5/16-18 UNC coarse thread pattern is widely used in both OEM assembly and repair work where standard inch-series fasteners are required. The zinc plating provides a surface barrier against light moisture exposure, making it appropriate for indoor mechanical enclosures, brackets, panels, and equipment frames. This SKU is sold individually but requires a minimum order quantity of 100 pieces per order.

Key Features

• 5/16-18 UNC coarse thread for reliable engagement in standard tapped holes
• Fully threaded shank for maximum thread engagement in shallow or through-hole applications
• 1/4-inch hex socket drive compatible with standard hex keys and hex bit drivers
• Alloy steel construction for higher strength versus standard carbon steel fasteners
• Zinc-plated finish meets ASTM B695 for basic corrosion protection
• 3/4-inch length under head suits thin-profile and medium-depth fastening applications

Compatibility

Designed as a standard-dimension replacement or replenishment fastener for any assembly requiring a 5/16-18 UNC fully threaded hex socket cap screw with a 3/4-inch length under head.

Installation Notes

Installation is performed with a 1/4-inch hex key or matching hex bit driver. Verify that the receiving tapped hole is clean, free of debris, and correctly sized for 5/16-18 UNC thread engagement before driving. Do not overtighten — follow the torque specifications published for the specific alloy steel grade used in your assembly documentation. Power down or de-energize any equipment before accessing fastened panels or enclosures.
