Value Collection -40231-1 Hex Socket Cap Screw 5/16-24

Product Description

The VALUE COLLECTION -40231-1 is a hex socket cap screw designed for secure fastening in applications requiring precise thread engagement and a low-profile head. This screw features a 5/16-24 UNF thread form, a 1/4 inch hex drive socket, and a length under head of 1.5 inches. It is fully threaded along its entire shank length. Constructed from alloy steel with a black oxide finish coating, it offers improved corrosion resistance and reduced glare compared to uncoated fasteners. It is suited for mechanical assemblies, tooling fixtures, and equipment maintenance tasks across industrial and trade applications.

This cap screw is used in applications where a recessed hex drive is preferred over an external hex head, allowing installation in countersunk or close-clearance locations. It is commonly installed during equipment assembly, machine repair, and structural fixturing in manufacturing, maintenance, and mechanical contracting environments. The 5/16-24 UNF fine thread pitch provides strong clamping force and resistance to loosening under vibration.

Key Features

• 5/16-24 UNF fine thread for high clamping force and vibration resistance
• Fully threaded shank with 1.5 inch length under head
• 1/4 inch hex socket drive for standard Allen key or hex bit installation
• Alloy steel construction for high tensile strength
• Black oxide coating for corrosion resistance and reduced surface glare
• Meets ASME/ANSI B18.3 and ASTM A574 fastener standards

Compatibility

Designed as an OEM-style replacement or direct-use hex socket cap screw for industrial assemblies, mechanical fixtures, and equipment requiring 5/16-24 UNF fully threaded socket head fasteners.

Installation Notes

Install using a properly sized 1/4 inch hex key or Allen bit driver. Ensure the mating threaded hole is clean and free of debris before installation. Power down and de-energize any equipment before servicing fasteners on electrical or mechanical assemblies. Follow applicable torque guidelines from the equipment manufacturer or relevant industry standards for 5/16-24 alloy steel fasteners.
