Type A tapping screws are designed for threading into pre-punched or pre-drilled sheet metal, light gauge steel, and similar materials without requiring a pre-tapped hole. The hex washer head provides a built-in bearing surface, improving clamping force and reducing fastener pull-through. The zinc coating delivers corrosion resistance suitable for general indoor and sheltered outdoor applications. These screws are a standard fastener used by HVAC technicians, sheet metal workers, and plumbers for securing panels, ductwork, brackets, and equipment enclosures.\u003c\/p\u003e\n\u003cp\u003eType A hex washer head tapping screws in No. 12 x 1 inch are widely used in residential and light commercial HVAC installations, plumbing rough-in work, and electrical enclosure assembly. Common applications include attaching sheet metal duct sections, securing access panels on air handlers and furnaces, fastening equipment mounting brackets, and general sheet metal fabrication. The jar packaging keeps fasteners organized on the job site and is suited for high-volume service work where multiple screws are consumed per visit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType A tapping thread profile cuts its own thread in pre-drilled or pre-punched sheet metal and light gauge substrates\u003c\/li\u003e\n  \u003cli\u003eHex washer head style provides a built-in washer bearing surface for increased pull-through resistance\u003c\/li\u003e\n  \u003cli\u003eNo. 12 x 1 inch size is a standard dimension widely used in HVAC ductwork and panel fastening\u003c\/li\u003e\n  \u003cli\u003eZinc finish provides corrosion resistance for general indoor and protected outdoor use\u003c\/li\u003e\n  \u003cli\u003eJar of 100 quantity keeps fasteners contained and accessible on the job site\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Type A hex washer head tapping screw for use in sheet metal, light gauge steel panels, and similar thin-material applications common in HVAC, plumbing, and electrical trade work.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a hex-head driver or nut driver sized to the fastener head. Ensure the substrate is pre-drilled or pre-punched to the correct pilot hole diameter for No. 12 Type A screws before driving. Do not over-torque, as stripping the self-tapped thread in thin sheet metal will compromise holding strength. Verify fastener material and finish compatibility with the substrate and surrounding environment before installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: No. 12\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 Head\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Type A Tapping\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity per Package\u003c\/strong\u003e: 100 (jar)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 662352111034\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: STEWART FASTENER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: J1216ACHZ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STEWART FASTENER","offers":[{"title":"Default Title","offer_id":51383193829682,"sku":"J1216ACHZ","price":22.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312670002.jpg?v=1782589284","url":"https:\/\/voomisupply.com\/products\/stewart-fastener-j1216achz-no-12x1-hex-washer-tapping-screw-zinc-100pk","provider":"Voomi Supply","version":"1.0","type":"link"}
