Value Collection 872233PR Hex Socket Cap Screw 5/16-24 Unf

Product Description

The VALUE COLLECTION 872233PR is a hex socket cap screw designed for precision fastening applications requiring a compact drive profile and controlled torque. With a 5/16-24 UNF thread size and 1 inch length under head, this fastener is fully threaded and driven by a 1/4 inch hex key. It is manufactured from alloy steel with a zinc-plated finish to resist corrosion in typical shop and field conditions. This screw meets ASME B18.8 and ASTM A574 standards, making it suitable for mechanical assemblies where dimensional accuracy and tensile strength are critical. It is commonly installed by machinists, millwrights, HVAC technicians, and general maintenance professionals working with equipment panels, brackets, and mechanical housings.

This socket cap screw is suited for light- to medium-duty fastening in residential and commercial applications where a low-profile head and recessed drive are needed. Typical use cases include securing access panels, motor mounts, bracket assemblies, and equipment enclosures in HVAC, plumbing, and general mechanical trade work. The fine 24-threads-per-inch UNF pitch provides strong holding power in thinner materials and improves resistance to loosening under vibration compared to coarse-thread equivalents.

Key Features

• 5/16-24 UNF fine-thread form for strong engagement and vibration resistance
• Fully threaded 1 inch length under head for maximum thread engagement
• 1/4 inch hex drive for use with standard hex keys and Allen drivers
• Alloy steel construction with zinc-plated finish for corrosion resistance
• Meets ASME B18.8 and ASTM A574 fastener standards
• Low-profile socket cap head suits recessed and tight-clearance installations

Compatibility

Designed as a standard 5/16-24 UNF hex socket cap screw for use in any mechanical assembly requiring an ASME B18.8 or ASTM A574 compliant fastener with a 1/4 inch hex drive and 1 inch length under head.

Installation Notes

Installation requires a 1/4 inch hex key or Allen driver; a T-handle or torque wrench with a hex bit is recommended for consistent seating. De-energize all equipment and relieve any system pressure before servicing fasteners in mechanical assemblies. Do not overtighten into tapped holes in soft materials such as aluminum; follow the equipment manufacturer torque specifications where provided. Minimum order quantity for this item is 100 pieces.
