L H Dottie Co RMDS1412 Round Head Square Drive Screw

Product Description

The L H Dottie Co RMDS1412 is a round head, square drive sheet metal screw with a 1/4 inch head diameter and 1/2 inch length. Designed for light-gauge sheet metal and general fastening applications, this screw uses a square drive recess to reduce bit cam-out during installation. It is a standard fastener used by electricians, HVAC technicians, and sheet metal workers in panel fabrication, ductwork, enclosures, and related trade work. The square drive design provides positive bit engagement and is compatible with standard square drive bits available in most trade toolkits.

This screw is suited for residential and commercial applications where a low-profile round head and reliable square drive engagement are needed. Typical uses include securing sheet metal panels, junction box covers, electrical enclosures, and HVAC duct components. Sold individually, it is appropriate for both small repair jobs and bulk fastening tasks where precise, repeatable installation is required.

Installation Notes

Installation is performed by qualified tradespeople including HVAC technicians, electricians, and sheet metal workers. Use the appropriate square drive bit to prevent slippage and surface damage. Ensure base material gauge is appropriate for the 1/2 inch screw length to achieve proper thread engagement without penetration through the far side. Power down any energized equipment before fastening near electrical components.
