Value Collection 011227PR Hex Socket Cap Screw 5/16-24 Unf

Product Description

The Value Collection 011227PR is a hex socket cap screw designed for precision fastening applications where a recessed drive and high clamping force are required. This fastener features a 5/16-24 UNF thread form with a 5/8-inch length under head and is fully threaded along its entire shank. It is driven by a 1/4-inch hex key. Constructed from alloy steel with a black oxide finish, it offers improved corrosion resistance compared to bare steel and is well suited to mechanical assemblies, machine components, and equipment maintenance tasks performed by maintenance technicians and industrial trades.

This screw is appropriate for use in tight-clearance applications where a standard hex head wrench cannot be used. The fine 5/16-24 UNF thread pitch provides greater thread engagement and finer torque control than coarse-thread equivalents, making it a common choice in precision mechanical assemblies, fixtures, and equipment housings. It meets the requirements of ASME/ANSI B18.3 and ASTM A574 fastener standards.

Key Features

• 5/16-24 UNF fine thread for increased thread engagement and precise torque adjustment
• Fully threaded shank along the entire 5/8-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 mechanical property requirements
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw suitable for general mechanical and industrial assembly applications requiring a 5/16-24 UNF fine-thread fastener.

Installation Notes

Installation should be performed by a qualified maintenance technician or machinist using a 1/4-inch hex key or appropriate bit driver. Ensure mating threads are clean and free of debris before installation. De-energize and lock out all equipment before servicing any fastened assemblies per applicable safety procedures. Do not substitute a coarse-thread fastener in a fine-thread tapped hole.
