Value Collection 011163P Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 011163P is a hex socket cap screw designed for high-strength fastening applications across industrial, mechanical, and trade installations. Threaded 1/4-20 UNC and measuring 2-1/4 inches in length under the head, this screw is partially threaded and driven with a 3/16-inch hex key. Constructed from alloy steel with a black oxide finish, it delivers solid corrosion resistance and meets ASME/ANSI B18.3 and ASTM A574 dimensional and mechanical standards. Maintenance technicians, millwrights, and general trade professionals install this type of fastener in equipment assemblies, machinery frames, and structural fixturing.

This screw is suited for applications requiring a recessed drive profile and a strong clamping load in a compact head footprint. The 1/4-20 UNC thread pitch is one of the most common inch-series thread standards, making this fastener widely applicable in general mechanical assemblies, HVAC equipment brackets, electrical enclosures, and pump or motor mounting situations. The black oxide coating reduces surface reflectivity and provides mild corrosion protection in dry to moderately humid environments. Partial threading allows for controlled clamping force against a mating surface without full thread engagement through the entire fastener body.

Key Features

• 1/4-20 UNC thread for compatibility with standard inch-series tapped holes
• 2-1/4-inch length under head with partial threading for positive clamping
• 3/16-inch hex drive socket for use with standard Allen keys or hex bit drivers
• Alloy steel construction meets ASTM A574 mechanical strength requirements
• Black oxide finish provides mild corrosion resistance and low-glare appearance
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as an OEM-style replacement or maintenance fastener for any application requiring a 1/4-20 UNC hex socket cap screw with a 2-1/4-inch length under head and a 3/16-inch drive.

Installation Notes

Install using a 3/16-inch hex key or Allen-type driver; ensure the mating tapped hole is clean and free of debris before threading. Power down and de-energize any equipment before replacing fasteners on electrical or mechanical assemblies. Do not exceed the rated mechanical load for the 1/4-20 thread class when torquing. Follow applicable equipment manufacturer guidelines and relevant codes for fastener installation in structural or pressure-bearing assemblies.
