Value Collection MP72108 Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION MP72108 is a hex socket cap screw designed for secure, high-torque fastening in mechanical assemblies, tooling fixtures, and equipment maintenance applications. Sized at 1/4-20 UNC with a 2-inch length under head, this partially threaded fastener accepts a 3/16-inch hex drive. Constructed from alloy steel with a black oxide finish, it delivers solid tensile strength and moderate corrosion resistance suitable for indoor and light industrial environments. Sold in a package of 25, it is well suited for shops, field technicians, and maintenance crews who need reliable grade fasteners on hand. Conforms to ASME B18.3 and ASTM A574 standards.

This fastener is used across a wide range of trades and maintenance scenarios, including HVAC equipment assembly, electrical panel mounting, pump and motor fastening, and general mechanical repairs. The partially threaded shank allows for precise clamping force between mated components without thread engagement through the full grip length. The black oxide coating reduces light reflection and provides a clean appearance in finished assemblies. Suitable for residential, commercial, and light industrial applications where a standard socket head cap screw is specified.

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw conforming to ASME B18.3 and ASTM A574, suitable for any application calling for this thread size and drive type.

Installation Notes

Install using a 3/16-inch hex key or socket bit driver; ensure the driver is fully seated before applying torque to avoid rounding the socket. Power down or de-energize any equipment before accessing fastened panels or components. Follow applicable equipment manufacturer torque specifications and relevant codes such as the NEC or IFGC where fasteners are used in code-governed assemblies. Do not substitute this fastener in structural or safety-critical joints without verifying grade and torque requirements against engineering specifications.
