Value Collection 581460PS Hex Socket Cap Screw 5/16-24

Product Description

The VALUE COLLECTION 581460PS is a partially threaded hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling fixtures, and structural components. Manufactured from alloy steel with a black oxide finish, this fastener meets the dimensional and mechanical requirements of ASME/ANSI B18.3 and ASTM A574. The 5/16-24 UNF thread provides fine-pitch engagement for applications requiring precise torque control and resistance to loosening under vibration. The 1/4 inch hex drive socket accepts a standard hex key or Allen driver. With a 6 inch length under head, this screw suits deeper clamping or through-bolt applications where extra thread engagement and grip length are required.

This fastener is suited for use in industrial machinery, equipment manufacturing, precision tooling, and maintenance applications across HVAC, electrical, and mechanical trades. The fine UNF thread series is commonly specified where vibration resistance and close-tolerance fits are needed. The black oxide coating provides mild corrosion resistance and reduces light reflection in applications where surface appearance matters. Installers working in fabrication shops, field service, or equipment assembly will find this screw appropriate for metal-to-metal fastening where a recessed drive is preferred over a hex head.

Key Features

• 5/16-24 UNF fine-pitch thread for high torque retention and vibration resistance
• 6 inch length under head accommodates deep clamping and through-bolt applications
• Alloy steel construction meets ASTM A574 mechanical strength requirements
• Black oxide finish provides mild corrosion resistance and low-glare surface
• 1/4 inch hex socket drive compatible with standard hex keys and Allen drivers
• Partially threaded shank for improved shear strength in structural fastening

Compatibility

Designed as an OEM-style and general-use replacement or addition for applications requiring a 5/16-24 UNF partially threaded hex socket cap screw conforming to ASME/ANSI B18.3 and ASTM A574 standards.

Installation Notes

Installation should be performed by a qualified technician familiar with fastener standards and proper torque procedures for alloy steel cap screws. Power down or de-energize any equipment before accessing fastener locations in live assemblies. Use a properly sized 1/4 inch hex key or driver to avoid rounding the socket drive. Verify thread engagement depth and ensure the mating tapped hole is clean and free of debris before installation.
