The hex washer head provides a broad bearing surface and allows for reliable torque application with a standard hex driver or nut driver. The self-tapping thread form cuts its own mating thread on installation, eliminating the need for a pre-tapped hole in compatible base materials. Licensed tradespeople and experienced installers handling sheet metal assemblies, equipment panels, and structural attachments will find this fastener suited to high-volume field work.\u003c\/p\u003e\u003cp\u003eThis tapping screw is commonly used in HVAC duct assembly, equipment enclosures, electrical panel trim, and light structural metal connections where a secure, vibration-resistant fastening point is required. The 3 inch length accommodates stacked or thicker material assemblies typical of commercial equipment installations. It is well suited for trade professionals working with sheet metal gauges common in HVAC and light construction environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 10 x 3 inch sizing for medium to heavy sheet metal fastening tasks\u003c\/li\u003e\n\u003cli\u003eHex washer head style allows high torque application and provides a built-in bearing washer surface\u003c\/li\u003e\n\u003cli\u003eSelf-tapping thread eliminates pre-tapping and speeds field installation\u003c\/li\u003e\n\u003cli\u003eCompatible with standard hex nut drivers and power screwdrivers\u003c\/li\u003e\n\u003cli\u003eSuited for HVAC ductwork, equipment panels, and general sheet metal assembly\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and general-use tapping screw for sheet metal fastening applications in HVAC, electrical, and light construction assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by HVAC technicians, sheet metal workers, or electricians using a hex nut driver or impact driver set to the appropriate clutch setting to avoid stripping the head or overdriving into thin gauge material. Always ensure the base material is clean and free of debris before driving the screw. Follow applicable local building codes and manufacturer guidelines for fastener spacing and pull-out load requirements. Do not reuse a self-tapping screw in the same hole, as thread engagement will be compromised.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: No. 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Hex Washer Head\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScrew Type\u003c\/strong\u003e: Self-Tapping\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: J1048ASHZ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STEWART FASTENER","offers":[{"title":"Default Title","offer_id":51345477632306,"sku":"J1048ASHZ","price":25.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310551975.jpg?v=1782059560","url":"https:\/\/voomisupply.com\/products\/stewart-fastener-j1048ashz-hex-washer-head-tapping-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
