Value Collection MP72106 Hex Socket Cap Screw 1/4-20 50pk

Product Description

The VALUE COLLECTION MP72106 is a hex socket cap screw designed for secure mechanical fastening in industrial, commercial, and trade applications. Threaded 1/4-20 UNC with a 1-3/4 inch length under head, this screw is partially threaded and accepts a 3/16 inch hex drive. Manufactured from alloy steel with a black oxide finish coating, it meets ASME B18.3 and ASTM A574 standards. The black oxide coating provides mild corrosion resistance and reduces light reflection in finished assemblies. This pack contains 50 screws, making it practical for production runs, maintenance kits, and job-site stock.

This screw is suited for use in mechanical assemblies, equipment fabrication, and structural fastening tasks where a recessed hex drive is required for flush or countersunk installation. Alloy steel construction handles high-tensile load applications typical in HVAC equipment mounting, electrical enclosure assembly, pump and motor installation, and general trade work. The 1/4-20 UNC thread is one of the most widely used coarse-thread fastener sizes in North American mechanical systems, making this screw a common stock item for service trucks and shop inventory.

Installation Notes

Installation is performed with a 3/16 inch hex key or hex bit driver; use a torque wrench where fastener preload is specified by the equipment manufacturer. Ensure the mating tapped hole is clean and properly threaded to the correct depth before driving. Power down and de-energize any electrical or mechanical equipment before accessing fastener locations on live systems. Follow applicable equipment manufacturer guidelines and relevant codes for fastener replacement in structural or pressure-bearing assemblies.
