Value Collection 015143PR Hex Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION 015143PR is a hex socket cap screw designed for secure fastening in mechanical assemblies, structural connections, and equipment maintenance applications. The screw features a 1/4-20 UNC thread size with full threading along its 3/8-inch length under head. Drive engagement is through a 3/16-inch hex socket. Constructed from alloy steel with a black oxide finish, it provides corrosion resistance and reduces light reflection in service environments. This fastener meets ASME/ANSI B18.3, ASTM A574, and IFI 124 standards, making it suitable for applications where dimensional and mechanical compliance is required. Machinists, millwrights, and maintenance technicians are the typical installers.

This socket cap screw is used across a wide range of industrial, mechanical, and trade applications including HVAC equipment assembly, electrical enclosure mounting, pump and motor maintenance, and general machinery repair. Its fully threaded shank makes it well suited for thin-material fastening where maximum thread engagement over the entire grip length is needed. The black oxide finish is compatible with oiled or dry service conditions. It is appropriate for both shop fabrication and field service work where a low-profile socket-drive fastener is required.

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw suitable for use wherever ASME/ANSI B18.3 and ASTM A574 compliant fasteners are specified. No specific equipment model compatibility was provided in the product data.

Installation Notes

Installation is performed with a 3/16-inch hex key or Allen driver; ensure the driver is fully seated before applying torque to avoid cam-out or socket rounding. Power down or de-energize any equipment before accessing fastener locations on live assemblies. Follow applicable mechanical codes and equipment manufacturer torque specifications for the joint material and thread class. Inspect threads for contamination or damage before installation to ensure proper seating and clamp load.
