Value Collection 581331PR Hex Socket Cap Screw 12-24 Unc

Product Description

The VALUE COLLECTION 581331PR is a hex socket cap screw designed for secure fastening in tight spaces where a standard hex wrench or Allen key is the primary drive tool. This screw features a 12-24 UNC thread size, a 1/2-inch length under head, and a 5/32-inch hex drive. It is fully threaded along its length, providing maximum thread engagement across the full fastened area. Constructed from alloy steel with a black oxide finish, it offers improved corrosion resistance compared to bare steel. Maintenance technicians, machine builders, and equipment assemblers typically install this fastener type in mechanical and industrial assemblies.

This screw is suited for use in general mechanical assemblies, industrial machinery, tool fixtures, and equipment enclosures requiring a compact drive profile. The 12-24 UNC thread pattern is a coarse unified national thread standard common in precision light machinery and instrument work. The black oxide coating reduces surface friction and provides a degree of corrosion protection in low-moisture environments. This fastener type is installed wherever flush or recessed head mounting is required and tool access is limited to a hex key.

Key Features

• 12-24 UNC thread size with full threading along the 1/2-inch body length under head
• 5/32-inch hex (Allen) drive for use in recessed or space-restricted mounting locations
• Alloy steel construction for high tensile strength in demanding mechanical applications
• Black oxide finish provides mild corrosion resistance and reduces light glare on exposed fastener heads
• Meets ASME/ANSI B18.3 and ASTM A574 standards for socket head cap screws

Compatibility

Designed as an OEM-style replacement or standard fastener for mechanical assemblies requiring 12-24 UNC socket head cap screws with a 1/2-inch length under head.

Installation Notes

Installation is performed using a 5/32-inch hex key or Allen driver. Ensure the mating threaded hole or nut is clean and free of debris before driving the screw. Apply appropriate thread-locking compound or torque per the host equipment manufacturer specifications. Always power down or de-energize equipment before accessing internal fastener locations in electrical or mechanical enclosures.
