Value Collection 011231PR Hex Socket Cap Screw 5/16-24 Unf

Product Description

The VALUE COLLECTION 011231PR is a hex socket cap screw designed for precision fastening applications requiring a compact, high-strength connection. The screw features a 5/16-24 UNF thread size with a 7/8 inch length under head and is fully threaded from head to end. The 1/4 inch hex drive accepts standard hex keys and Allen wrenches for installation in tight clearance areas. Constructed from alloy steel with a black oxide finish, this fastener delivers solid corrosion resistance in moderate environments and meets ASME/ANSI B18.3 and ASTM A574 dimensional and mechanical standards. Maintenance technicians, machinists, and trade professionals use this fastener type across HVAC, mechanical, and general industrial assembly work.

This screw suits applications where a flush or recessed fastener head is needed and torque must be applied with a hex key rather than an external wrench. The fully threaded shank provides maximum thread engagement across the clamped material thickness, making it well suited for thin-stock assemblies and close-tolerance mechanical joints. Typical use cases include equipment panels, bracket mounting, motor mounting flanges, and general mechanical subassembly work in commercial and industrial settings.

Key Features

• 5/16-24 UNF thread for fine-pitch engagement and vibration resistance
• 7/8 inch length under head with full threading along the entire shank
• 1/4 inch hex drive compatible with standard Allen keys and hex bit drivers
• Alloy steel construction meets ASTM A574 mechanical requirements
• Black oxide coating provides moderate corrosion resistance and reduces light reflection
• Conforms to ASME/ANSI B18.3 dimensional standard for socket cap screws

Compatibility

Designed as a standard ASME/ANSI B18.3 socket cap screw suitable for use in any application calling for a 5/16-24 UNF fully threaded hex socket fastener with a 7/8 inch length under head.

Installation Notes

Installation requires a 1/4 inch hex key or Allen bit driver. Ensure mating threaded holes are clean and free of debris before driving. Apply appropriate thread-locking compound or torque to specification per the equipment manufacturer's service documentation. Alloy steel fasteners should not be used in direct contact with dissimilar metals in wet environments without additional corrosion protection.
