Value Collection 31844 5/16-18 Unc Hex Thread Cutting Screw 50pk

Product Description

The VALUE COLLECTION 31844 is a 5/16-18 UNC hex head thread cutting screw designed for creating threads in pre-drilled holes in metal, making it a reliable fastener for mechanical assembly and fabrication work. Built from Grade 2 steel with a zinc-plated finish for corrosion resistance, this screw features a Type F point that cuts threads as it drives, eliminating the need for tapping in many applications. The hex head drive style allows for high torque application using standard wrenches or sockets. This package contains 50 screws, suited for shop stock, field service kits, or production use.

This screw is used in light to medium-duty metalworking, HVAC equipment assembly, electrical panel fabrication, and general mechanical installations where a self-threading fastener is needed in steel or similar materials. The 5/16-18 UNC thread size and 3/4 inch length under head make it suitable for thin to medium material thicknesses. Tradespeople in HVAC, electrical, and plumbing fields commonly use this fastener when assembling equipment enclosures, mounting brackets, and junction boxes.

Installation Notes

Installation is performed by qualified technicians or tradespeople using a wrench or socket sized for the hex head. Always pre-drill the correct pilot hole diameter for a 5/16-18 UNC Type F thread cutting screw before driving to avoid material damage or fastener failure. Power down or de-energize any equipment before installing fasteners in or near electrical enclosures. Follow applicable codes and equipment manufacturer guidelines for fastener torque and hole preparation.
