Sized at number 8 diameter by 0.5 inches in length and zinc plated for corrosion resistance, this screw features a sharp tapered point that pierces sheet metal without pre-drilling. The heat-treated construction ensures the point does not mushroom, break, or walk during installation. The combination lead double thread engages quickly and holds securely. HVAC installers and sheet metal mechanics working in duct fabrication shops or on-site assembly will find this screw suited for high-volume production use. This bulk pail contains 12000 screws.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in light-gauge sheet metal joining applications common to HVAC ductwork, fittings, and sheet metal enclosures. The slotted hex washer head allows drive with either a hex driver or flat-blade bit, giving installers flexibility on the job. The undercut-indented hex washer head design provides a burr-free bearing surface that seats flush against the metal. Typical installers include sheet metal mechanics, HVAC technicians, and duct fabricators working on residential and light commercial systems where high fastener volume is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSelf-piercing sharp tapered point — no pre-drilling required\u003c\/li\u003e\n  \u003cli\u003eHeat-treated construction resists point mushrooming, breakage, and walking\u003c\/li\u003e\n  \u003cli\u003eCombination lead double thread for fast engagement and secure hold\u003c\/li\u003e\n  \u003cli\u003eBurr-free undercut-indented hex washer slotted head for clean seating\u003c\/li\u003e\n  \u003cli\u003eZinc plated finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eBulk pail quantity of 12000 screws suited for high-volume production use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in light-gauge sheet metal fastening applications including HVAC ductwork fabrication, sheet metal fittings, and metal enclosure assembly.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSheet metal mechanics and HVAC technicians typically install these screws using a hex driver or flat-blade bit with a variable-speed drill or screw gun. No pilot hole is required due to the self-piercing point design. Ensure the workpiece is properly supported and clamped before driving to maintain precise hole alignment.
