Value Collection -40235-5 Hex Socket Cap Screw 5/16-24 Unf

Product Description

The VALUE COLLECTION -40235-5 is a partially threaded hex socket cap screw designed for high-strength fastening applications across industrial, mechanical, and trade service work. It features a 5/16-24 UNF thread size and measures 4 inches in length under the head. The screw is manufactured from alloy steel and finished with a black oxide coating for corrosion resistance and reduced light reflection. Drive engagement is via a 1/4-inch hex socket drive. This fastener is commonly installed by millwrights, maintenance technicians, and field service pros working on equipment assemblies, brackets, and machine components.

This cap screw is suited for applications requiring a fine-thread fastener in steel or aluminum assemblies where vibration resistance and precise torque control are priorities. The partial threading allows the unthreaded shank to act as a locating or shear surface within a bore. It is appropriate for residential and commercial mechanical equipment maintenance as well as OEM-style repair work on fabricated assemblies requiring ASME/ANSI B18.3 and ASTM A574 compliant hardware.

Key Features

• 5/16-24 UNF fine-thread profile for precise thread engagement and vibration resistance
• Partially threaded shank serves as a shear or locating surface within bored holes
• Alloy steel construction meets ASTM A574 high-strength socket screw standard
• Black oxide finish provides mild corrosion resistance and low-glare surface
• 1/4-inch hex socket drive for standard Allen key or hex bit installation
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard-compliance replacement or service fastener for mechanical assemblies requiring a 5/16-24 UNF partially threaded hex socket cap screw per ASME/ANSI B18.3 and ASTM A574 specifications.

Installation Notes

Installation is performed using a 1/4-inch hex key or hex socket bit driver. De-energize and lock out any equipment before replacing fasteners on live machinery per applicable OSHA lockout/tagout procedures. Verify thread engagement depth and hole condition before driving to full seating. Do not substitute metric tooling for the 1/4-inch hex drive, as rounding the socket can damage the fastener head.
