Value Collection 872229PR Hex Socket Cap Screw 5/16-24 Unf

Product Description

The VALUE COLLECTION 872229PR is a hex socket cap screw designed for secure, high-torque fastening in mechanical and structural assemblies. It features a 5/16-24 UNF thread size with full threading along its 3/4-inch length under head, accepting a 1/4-inch hex drive. Constructed from alloy steel with a zinc-plated finish, this fastener delivers corrosion resistance and the tensile strength required for demanding trade and industrial applications. It conforms to ASME B18.8 and ASTM A574 standards, making it a reliable choice for precision-fit installations where dimensional consistency matters.

This cap screw is suited for use in HVAC equipment assemblies, pump housings, motor mounts, electrical enclosures, and general mechanical fabrication where a recessed hex drive is preferred over external-drive fasteners. The fine 24-thread-per-inch UNF pitch provides tighter clamping in thinner materials and vibration-prone environments. Sold individually with a minimum order quantity of 100 units, this fastener is appropriate for shop stock, maintenance kits, and production line use across mechanical and trade applications.

Key Features

• 5/16-24 UNF fine thread for strong clamping in thin or vibration-exposed material
• Fully threaded along the 3/4-inch length under head
• 1/4-inch hex socket drive for recessed, torque-efficient installation
• Alloy steel construction with zinc-plated finish for corrosion resistance
• Meets ASME B18.8 and ASTM A574 dimensional and mechanical standards

Compatibility

Designed as an OEM-style replacement or stock fastener for mechanical assemblies requiring a 5/16-24 UNF fully threaded hex socket cap screw with a 3/4-inch length under head.

Installation Notes

Installation is typically performed by machinists, millwrights, HVAC technicians, or licensed tradespeople using a calibrated hex key or socket driver. Always de-energize and lock out equipment before fastener replacement in electrical or mechanical systems. Use a torque wrench appropriate for the alloy steel grade to avoid overtightening and thread damage. Verify thread engagement and hole condition before installation to ensure a secure fit.
