Value Collection 015351PR Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION 015351PR is a hex socket cap screw designed for high-strength fastening applications across industrial, mechanical, and structural assemblies. Sized at 1/2-13 UNC with a 3/4-inch length under head and fully threaded shank, this fastener is manufactured from alloy steel and finished with a black oxide coating for corrosion resistance and reduced light reflection. The 3/8-inch hex drive allows installation with a standard hex key or Allen-drive socket. Sold in a minimum order quantity of 10 pieces, this screw suits shops, MRO operations, and contractors needing reliable high-tensile fasteners in volume.

This cap screw is suited for machine assembly, equipment mounting, jigs and fixtures, and general industrial maintenance where a flush or low-profile fastener head is required. The 1/2-13 UNC coarse thread pattern provides strong engagement in steel and cast iron tapped holes and is compatible with standard UNC hex nuts and threaded inserts. The black oxide finish makes it a common choice in applications where hardware aesthetics or light control matter alongside mechanical performance.

Key Features

• Fully threaded shank with 1/2-13 UNC coarse thread for maximum engagement in shallow tapped holes
• 3/4-inch length under head suits compact joint stacks and close-clearance assemblies
• Alloy steel construction provides high tensile and shear strength
• Black oxide finish offers mild corrosion resistance and a non-reflective appearance
• 3/8-inch hex drive compatible with standard hex keys and socket drivers
• Meets ASME/ANSI B18.3, ASTM A574, and IFI 124 fastener standards

Compatibility

Designed as an OEM-style and general-use replacement or supplement fastener for any assembly requiring a 1/2-13 UNC hex socket cap screw with a 3/4-inch length under head.

Installation Notes

Installation is performed with a 3/8-inch hex key or Allen-drive bit; ensure the drive tool is fully seated before applying torque to avoid rounding the socket. Always verify the tapped hole thread condition and depth before installation. De-energize and lock out any equipment before replacing fasteners on live machinery per standard OSHA lockout/tagout procedures. Black oxide finish provides only mild corrosion protection — apply thread lubricant or anti-seize compound in wet or outdoor environments if needed.
