Sized at 8-18 x 3\/4 inches with a hex washer head, this screw drills its own pilot hole and taps its own thread in a single operation, eliminating the need for pre-drilling. Constructed from hardened steel with a zinc finish for corrosion resistance, it is suited for light-gauge sheet metal work in HVAC ductwork, electrical enclosures, and similar trade applications. Each pack contains 75 screws.\u003c\/p\u003e\n\u003cp\u003eThis screw is commonly used by HVAC technicians, electricians, and sheet metal workers during installation and service of light-gauge metal assemblies. The hex washer head provides a bearing surface that distributes load and allows drive with a standard nut driver or hex bit. The 8-18 thread form and hardened steel construction make it appropriate for securing duct sections, electrical boxes, metal framing, and light structural sheet metal components in both residential and commercial settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSelf drilling tip eliminates pre-drilling and tapping steps\u003c\/li\u003e\n  \u003cli\u003eHex washer head is compatible with standard nut drivers and hex bit drivers\u003c\/li\u003e\n  \u003cli\u003eHardened steel construction provides strength in sheet metal applications\u003c\/li\u003e\n  \u003cli\u003eZinc finish offers corrosion resistance for typical indoor and enclosed installations\u003c\/li\u003e\n  \u003cli\u003e75-count pack suits jobsite and service-van stocking\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose 8-18 x 3\/4 inch self drilling fastener for light-gauge sheet metal applications typical in HVAC, electrical, and related trade work.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a hex nut driver or hex bit and standard power drill or impact driver set to a controlled torque to avoid stripping the head or overdriving through thin material.
