Self-tapping screws cut their own threads as they are driven, eliminating the need for a pre-tapped hole in sheet metal, light-gauge steel, and similar substrates. The hex head drive style allows use with a standard nut driver or hex bit, providing consistent torque application. These screws are used across HVAC, electrical, plumbing, and general trade applications where secure, fast fastening in thin materials is required.\u003c\/p\u003e\u003cp\u003eThese screws are well suited for light-gauge sheet metal work common in HVAC duct fabrication, equipment panels, electrical enclosures, and other trade installations. The zinc plating provides corrosion resistance appropriate for indoor and sheltered outdoor applications. The 100-count jar format keeps fasteners organized and accessible on the job site or service van, making them practical for both service technicians and installation crews handling repetitive fastening tasks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 8 diameter self-tapping design cuts threads on installation without pre-tapping\u003c\/li\u003e\n\u003cli\u003e1-1\/4 inch length suits light-gauge sheet metal and panel fastening\u003c\/li\u003e\n\u003cli\u003eZinc plating provides corrosion resistance for indoor and sheltered applications\u003c\/li\u003e\n\u003cli\u003eHex head drive compatible with standard nut drivers and hex bit drivers\u003c\/li\u003e\n\u003cli\u003e100-count jar packaging keeps fasteners contained and ready for field use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose self-tapping fastener for light-gauge sheet metal, equipment panels, and similar substrates commonly encountered in HVAC, electrical, and mechanical trade work.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed with a nut driver or hex-head bit at appropriate drill speed to avoid stripping the self-tapped thread. Ensure the substrate material and gauge are appropriate for a No. 8 self-tapping screw before driving. Do not overdrive; stop when the head seats flush to avoid damaging the fastener or substrate.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: No. 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Hex\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Self-Tapping\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc Plated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity per Package\u003c\/strong\u003e: 100 screws per jar\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 662352110891\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: J0820ACHZ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STEWART FASTENER","offers":[{"title":"Default Title","offer_id":51344446980402,"sku":"J0820ACHZ","price":24.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310552001.jpg?v=1782036269","url":"https:\/\/voomisupply.com\/products\/stewart-fastener-j0820achz-zinc-hex-self-tap-screw-no-8","provider":"Voomi Supply","version":"1.0","type":"link"}
