It features a hex washer head driven by a hex drive and a No. 4 drill point that cuts its own pilot hole without pre-drilling. The shank measures 7\/8 inches in length under the head. Constructed from steel with a zinc-plated finish, it resists corrosion in typical indoor and light outdoor environments. Electricians, HVAC installers, sheet metal workers, and general contractors commonly use this screw type for securing panels, brackets, and ductwork components.\u003c\/p\u003e\u003cp\u003eThis screw is suited for sheet metal fabrication, HVAC duct assembly, electrical enclosure installation, and light structural metal fastening. The hex washer head provides a wide bearing surface that distributes clamping load and reduces material distortion. The No. 4 drill point is designed for use in light-gauge steel applications where speed and consistency are priorities on the job.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 12 screw size for medium-duty metal fastening applications\u003c\/li\u003e\n\u003cli\u003eNo. 4 drill point cuts its own pilot hole in light-gauge steel\u003c\/li\u003e\n\u003cli\u003eHex washer head with hex drive for positive tool engagement and high torque transfer\u003c\/li\u003e\n\u003cli\u003e7\/8 inch length under head suits standard light-gauge sheet metal assemblies\u003c\/li\u003e\n\u003cli\u003eSteel construction with zinc-plated finish for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eInch measurement system for compatibility with standard trade tooling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard No. 12 self-drilling screw for light-gauge sheet metal and general trade fastening applications where a hex washer head and No. 4 drill point are specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed with a hex-drive bit in a variable-speed drill or impact driver set to an appropriate clutch setting to avoid overdriving.
