Value Collection 581464PR Hex Socket Cap Screw 3/8-16 Unc

Product Description

The VALUE COLLECTION 581464PR is an alloy steel hex socket cap screw designed for high-strength fastening applications across mechanical, industrial, and trade installations. It features a 3/8-16 UNC thread profile and measures 1-1/8 inches under the head with full threading along the shank. A 5/16-inch hex drive accepts a standard Allen key or hex bit. The black oxide finish provides a baseline level of corrosion resistance and reduces light reflection in finished assemblies. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards, making it suitable where dimensional and strength specifications must be verified.

This cap screw is used in general mechanical assembly, equipment manufacturing, and maintenance applications where a low-profile socket head is required. The fully threaded 3/8-16 UNC configuration suits through-bolt and tapped-hole installations in steel, aluminum, and other structural materials. Typical installers include millwrights, pipefitters, HVAC technicians, and maintenance mechanics working on equipment frames, brackets, and component mounting. It is sold individually by unit but requires a minimum order of 100 pieces.

Key Features

• 3/8-16 UNC thread size for broad compatibility with standard tapped holes
• 1-1/8 inch length under head, fully threaded for maximum thread engagement
• 5/16-inch hex drive accepts standard Allen keys and hex bit drivers
• Alloy steel construction rated to ASTM A574 for high tensile strength
• Black oxide coating reduces surface corrosion and glare in finished assemblies
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as an OEM-style replacement or standard fastener for any application calling for a 3/8-16 UNC hex socket cap screw with a 1-1/8 inch under-head length and 5/16-inch drive, per ASME/ANSI B18.3 and ASTM A574 specifications.

Installation Notes

Installation is performed with a 5/16-inch hex key or hex drive bit; ensure the drive tool is fully seated before applying torque to prevent rounding the socket. Verify the tapped hole thread specification matches 3/8-16 UNC before fastening. Power down or de-energize any equipment being serviced before installing or removing fasteners on live assemblies. Follow applicable industry standards and equipment manufacturer guidelines for proper torque procedures.
