Value Collection 011151P Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 011151P is a hex socket cap screw designed for secure fastening in mechanical, structural, and industrial assemblies. It features a 1/4-20 UNC thread profile and measures 7/8 inches in length under the head with full threading along the shank. The drive is a 3/16-inch internal hex socket, requiring an Allen key or hex driver for installation. Manufactured from alloy steel with a black oxide finish, this screw delivers solid tensile strength and moderate corrosion resistance in controlled environments. It meets ASME/ANSI B18.3 and ASTM A574 standards, making it a reliable choice for precision mechanical applications where dimensional accuracy is required.

This screw is suited for use in machinery, equipment enclosures, fixtures, jigs, and general fabrication work where a low-profile cap screw with a recessed drive is preferred. The fully threaded shank allows engagement along the full fastener length, making it effective in through-hole and blind-hole configurations. Typical installers include machinists, millwrights, maintenance technicians, and mechanical assemblers working in light to heavy industrial settings.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard tapped holes
• 7/8 inches length under head with full threading along the shank
• 3/16-inch hex socket drive for secure torque transfer with minimal cam-out
• Alloy steel construction meets ASTM A574 mechanical requirements
• Black oxide finish provides mild corrosion resistance and reduced light reflection
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw for use in any tapped hole or threaded insert conforming to UNC thread standards per ASME/ANSI B18.3.

Installation Notes

Installation requires a 3/16-inch hex key or Allen driver; an appropriately rated torque wrench is recommended to avoid over-torquing the alloy steel shank. Ensure mating threads are clean and free of debris before fastening. De-energize and lock out any equipment before performing fastener service on live machinery per applicable workplace safety standards.
