Value Collection 581444PS Hex Socket Cap Screw 5/16-24 Unf

Product Description

The VALUE COLLECTION 581444PS is a hex socket cap screw designed for secure fastening in precision mechanical assemblies. It features a 5/16-24 UNF thread, a 3/8 inch length under head, and a 1/4 inch hex drive. Constructed from alloy steel with a black oxide finish, this screw delivers high tensile strength and moderate corrosion resistance. It is fully threaded along its entire length, providing consistent clamp load across the full engagement depth. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards, making it appropriate for demanding structural and mechanical applications where dimensional accuracy and strength are required.

This socket cap screw is suited for use in general industrial, mechanical, and maintenance applications where a low-profile, high-strength fastener is needed. The fine 24-pitch UNF thread provides superior holding strength in thin-walled assemblies and improves resistance to loosening under vibration. It is commonly installed in machine frames, fixtures, tooling, and precision equipment. Maintenance technicians and millwrights typically use this fastener in both OEM assembly and field repair contexts.

Key Features

• 5/16-24 UNF fine thread for improved holding strength in vibration-prone assemblies
• Fully threaded shank maximizes thread engagement over the 3/8 inch length under head
• 1/4 inch hex socket drive for use with standard Allen keys or hex bit drivers
• Alloy steel construction meets ASTM A574 high-strength fastener requirements
• Black oxide finish provides mild corrosion resistance and reduced surface glare
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw suitable for any application requiring a 5/16-24 UNF fully threaded fastener with a 1/4 inch hex drive.

Installation Notes

Install using a correctly sized 1/4 inch hex key or socket bit to avoid rounding the drive recess. Ensure mating threads are clean and free of debris before installation. Apply thread-locking compound or seating torque per the equipment manufacturer's specifications. De-energize and lock out any machinery before fastener replacement in live equipment.
