Value Collection 88546650 Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 88546650 is a 1/4-20 UNC hex socket cap screw designed for mechanical fastening applications where a low-profile, high-strength threaded fastener is required. Made from alloy steel with a black oxide finish, this screw offers improved corrosion resistance and reduced light reflection compared to bare steel. The 3/16 inch hex drive socket head accepts a standard hex key or Allen wrench, and the partially threaded shank provides clamping strength across the grip length. Each package contains 13 screws, making it a practical quantity for shop stock or job-site use by machinists, millwrights, maintenance technicians, and general contractors.

This cap screw is suited for use in machinery assembly, fixture building, jig fabrication, and equipment maintenance across industrial and commercial settings. The 1/4-20 UNC thread is one of the most common unified coarse thread sizes in North American trade work, giving this fastener broad utility in metal-to-metal clamping, equipment panels, and structural sub-assemblies. The black oxide coating makes it a common choice where a darker finish is preferred for aesthetics or minimal surface glare.

Key Features

• 1/4-20 UNC thread — one of the most widely used unified coarse thread sizes in trade and industrial work
• 5/8 inch length under head for reliable grip in standard material thicknesses
• 3/16 inch hex socket drive accepts standard hex keys and Allen wrenches
• Partially threaded shank provides stronger clamping force across the unthreaded grip zone
• Alloy steel construction offers higher tensile strength than standard carbon steel fasteners
• Black oxide finish provides mild corrosion resistance and a uniform dark appearance

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw for use in any application requiring this thread size and drive type. Verify thread engagement depth and shank clearance before installation.

Installation Notes

Installation requires a 3/16 inch hex key or T-handle Allen wrench. Ensure mating threads are clean and free of debris before driving. Torque to the values specified by your equipment manufacturer or applicable industry standards — do not over-torque alloy steel fasteners in soft or tapped aluminum housings. Power down or de-energize any equipment before accessing fasteners on live assemblies.
