Supplied in a 100-piece pail, each screw is zinc plated and heat treated for corrosion resistance and mechanical strength. The sharp tapered point pierces sheet metal without pre-drilling and is engineered to resist mushrooming, breaking, or walking during installation. The undercut-indented hex washer slotted head provides a burr-free seating surface and allows combination drive tool use for added flexibility on the job.\u003c\/p\u003e\n\u003cp\u003eThese screws are suited for HVAC ductwork fabrication and assembly, sheet metal enclosure work, and light structural sheet metal connections in both residential and commercial applications. The double-thread lead and sharp point geometry give the installer precise hole alignment and full operator control through the fastening cycle. HVAC fabricators, sheet metal mechanics, and ductwork installers working with standard gauge duct sections will find these a reliable stock fastener for high-volume assembly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSelf-piercing sharp tapered point — no pre-drilling required on light-gauge sheet metal\u003c\/li\u003e\n  \u003cli\u003eBurr-free hex washer slotted head with undercut-indented design for clean seating\u003c\/li\u003e\n  \u003cli\u003eCombination lead double thread for fast engagement and precise alignment\u003c\/li\u003e\n  \u003cli\u003eZinc plated finish provides corrosion resistance in typical HVAC and sheet metal environments\u003c\/li\u003e\n  \u003cli\u003eHeat treated construction resists point mushrooming and head breakage under torque\u003c\/li\u003e\n  \u003cli\u003e100-piece pail quantity suited for high-volume ductwork and fabrication work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard stock fastener for light-gauge sheet metal assembly work, including residential and commercial HVAC ductwork fabrication and sheet metal enclosure construction.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSheet metal mechanics and HVAC technicians should use a hex driver or slotted bit matched to the head style to maintain full operator control and avoid cam-out. No pre-drilling is required for standard light-gauge sheet metal; verify base material gauge before use to confirm self-piercing compatibility. Fasten to appropriate torque for the gauge and application — do not overdrive, as this can strip the hole or distort the washer face. Follow applicable sheet metal and ductwork assembly standards for fastener spacing and pattern.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: #8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Style\u003c\/strong\u003e: Hex Washer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Style\u003c\/strong\u003e: Slotted\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProcess\u003c\/strong\u003e: Heat Treated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity\u003c\/strong\u003e: 100 per pail\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MALCO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HW8X1Z-100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MALCO","offers":[{"title":"Default Title","offer_id":51284125942066,"sku":"HW8X1Z-100","price":16.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309278543.jpg?v=1781069193","url":"https:\/\/voomisupply.com\/products\/malco-hw8x1z-100-sheet-metal-screw-8x1-in-zinc-100pk","provider":"Voomi Supply","version":"1.0","type":"link"}
