Value Collection 581339PR Hex Socket Cap Screw 12-24 Unc

Product Description

The VALUE COLLECTION 581339PR is a hex socket cap screw designed for secure, high-torque fastening in mechanical assemblies and structural applications. It features a 12-24 UNC thread size with a 1-1/4 inch length under head and a 5/32 inch hex drive. Constructed from alloy steel with a black oxide finish, it delivers solid corrosion resistance and tensile strength for demanding service conditions. This screw is fully threaded from tip to head, making it suitable for through-hole and threaded-insert installations. It is handled by machinists, millwrights, and maintenance technicians across industrial and commercial settings.

This fastener is suited for use in machine assembly, equipment maintenance, and precision fabrication work where a flush or countersunk socket-drive fastener is required. The 12-24 UNC coarse thread pattern offers reliable engagement in steel, aluminum, and other common structural materials. The black oxide coating provides mild corrosion protection and reduces light glare on exposed hardware. It fits standard 5/32 inch hex keys and Allen wrenches, which are commonly stocked in maintenance and shop environments.

Key Features

• 12-24 UNC coarse thread for reliable engagement in common metals
• 1-1/4 inch length under head for sufficient thread engagement depth
• 5/32 inch hex socket drive compatible with standard Allen keys
• Fully threaded from tip to head for maximum fastening flexibility
• Alloy steel construction meets ASME/ANSI B18.3 and ASTM A574 standards
• Black oxide finish provides mild corrosion resistance and low-glare appearance

Compatibility

Designed as an OEM-style replacement or standard-stock hex socket cap screw for machinery, equipment panels, and fabricated assemblies requiring a 12-24 UNC thread pattern with a 5/32 inch hex drive.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a 5/32 inch hex key or Allen wrench. De-energize or lock out equipment before servicing fasteners on live mechanical assemblies per applicable OSHA lockout/tagout procedures. Ensure mating threads are clean and free of debris before installation. Do not exceed the rated drive torque for the thread size to avoid stripping or fastener failure.
