Value Collection KP25097 Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION KP25097 is a hex socket cap screw designed for secure fastening in mechanical, industrial, and trade applications. The screw features a 1/4-20 UNC thread size with full threading along its 5/16-inch length under head. Drive engagement is handled by a 3/16-inch hex socket. Constructed from alloy steel with a black oxide finish coating, it meets ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for high-strength fastening tasks where dimensional precision and material integrity are required. Sold in a package of 25 units.

This screw is used across a wide range of mechanical assembly, equipment maintenance, and installation tasks common to HVAC, electrical, plumbing, and general industrial work. The 1/4-20 UNC thread is one of the most common unified coarse thread sizes and fits a broad variety of tapped holes in metal components. The black oxide finish provides mild corrosion resistance and reduces light reflection in finished assemblies. Suitable for interior applications and protected environments where moderate corrosion resistance is acceptable.

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw for use in any application requiring an ASME/ANSI B18.3 compliant fastener with a 5/16-inch length under head and 3/16-inch hex drive.

Installation Notes

Install using a 3/16-inch hex key or Allen-style bit driver. Ensure the tapped receiving hole is clean and free of debris before threading. Power down or de-energize any equipment before accessing fastener locations on live mechanical or electrical assemblies. Follow applicable ANSI and facility maintenance standards for fastener replacement and torque procedures.
