Value Collection -40230-1 Hex Socket Cap Screw 5/16-24 Unf

Product Description

The VALUE COLLECTION -40230-1 is a hex socket cap screw designed for secure fastening in applications where a low-profile, high-strength connection is required. The screw features a 5/16-24 UNF thread with a 1-1/4 inch length under head, fully threaded along its entire shaft. Drive engagement is achieved through a 1/4 inch hex socket. Constructed from alloy steel with a black oxide coating, the fastener resists corrosion and maintains surface integrity under moderate environmental exposure. This part meets ASME/ANSI B18.3 and ASTM A574 standards, confirming dimensional and mechanical compliance for commercial and industrial use.

This hex socket cap screw is suited for mechanical assemblies, equipment mounting, and structural fastening tasks across manufacturing, maintenance, and industrial service environments. Its fine 5/16-24 UNF thread pitch allows for precise torque adjustment and improved resistance to vibration loosening compared to coarse-thread alternatives. The black oxide finish makes it appropriate for interior or lightly protected installations. Typically installed by maintenance technicians, millwrights, or field service professionals using a 1/4 inch hex key or allen wrench driver.

Key Features

• 5/16-24 UNF fine thread for precise engagement and vibration resistance
• 1-1/4 inch length under head, fully threaded for maximum thread engagement
• 1/4 inch hex socket drive for use with standard allen keys or socket drivers
• Alloy steel construction meets ASTM A574 mechanical requirements
• Black oxide finish provides corrosion resistance and reduces light reflection
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard 5/16-24 UNF hex socket cap screw per ASME/ANSI B18.3, suitable for use in any application requiring a conforming fastener of this thread size, drive type, and length.

Installation Notes

Install using a calibrated 1/4 inch hex key or socket driver. Ensure mating threads are clean and free of debris before installation. Do not exceed the torque rating specified by the assembly manufacturer for 5/16-24 alloy steel fasteners. Inspect the black oxide coating for damage prior to installation in corrosive or wet environments; apply supplemental corrosion protection if required by the application.
