Each screw measures No. 8 diameter by 3\/4 inches in length, features 18 threads per inch (TPI), and is driven with a 1\/4-inch hex drive. The integrated No. 2 drill point eliminates the need for a separate pilot hole, producing an optimum hole size for better thread engagement and a tighter fit. Screws are cold forged for consistent dimensional uniformity and precise drill point contour. Heat-treated steel construction provides reliable holding strength across a wide range of field conditions. This bulk pack contains 100 screws.\u003c\/p\u003e\n\u003cp\u003eThese bit-tip screws are suited for HVAC duct fabrication, sheet metal assembly, and light structural fastening where self-drilling capability saves time and reduces the need for auxiliary equipment such as drill bits or welding setups. The 1\/4-inch hex drive makes them compatible with standard power screwdrivers and magnetic hex nut drivers commonly used by HVAC technicians and sheet metal workers. The hex washer head provides a wide bearing surface and positive drive engagement on metal substrates.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo. 2 drill point produces an optimum pilot hole for improved thread engagement and holding strength\u003c\/li\u003e\n  \u003cli\u003eCold-forged construction ensures uniformity of dimensions and drill point contour across the full 100-piece bulk pack\u003c\/li\u003e\n  \u003cli\u003eHeat-treated steel for added hardness and durability in demanding fastening applications\u003c\/li\u003e\n  \u003cli\u003eHex washer head provides a wide bearing surface and resists cam-out during installation\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch hex drive is compatible with standard power drivers and nut drivers\u003c\/li\u003e\n  \u003cli\u003eEliminates the need for separate drill bits or welding equipment, reducing setup time on the job\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style self-drilling fastener for sheet metal and light-gauge steel applications commonly encountered in HVAC duct work and metal fabrication installations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by HVAC technicians or sheet metal workers using a 1\/4-inch hex drive power screwdriver or drill. Ensure the work material is secured before driving screws to prevent movement that could affect thread engagement. Do not overdrive — excessive torque can strip threads or damage the hex washer head bearing surface. Follow applicable mechanical and building codes for fastener spacing and load requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: No. 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch (TPI)\u003c\/strong\u003e: 18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Style\u003c\/strong\u003e: 1\/4 inch Hex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Style\u003c\/strong\u003e: Hex Washer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Size\u003c\/strong\u003e: No. 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\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 Bulk Pack\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: Lifetime Limited\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: BT133-100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MALCO","offers":[{"title":"Default Title","offer_id":51284062241074,"sku":"BT133-100","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309278260.jpg?v=1781067537","url":"https:\/\/voomisupply.com\/products\/malco-bt133-100-hex-washer-bit-tip-screw-100-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
