The screw features a slotted hex washer head measuring 0.322 to 0.348 inches in diameter, a sharp point for self-piercing entry, and a 15 threads-per-inch DWF thread form. The 1\/4-inch hex head is engineered to resist cam-out and stripping under power-driver torque. Made from carbon steel with a zinc plated finish for corrosion resistance, these screws are bulk packed for high-volume trade use. HVAC technicians, plumbers, and electricians reach for this fastener when securing light-gauge sheet metal assemblies on the job.\u003c\/p\u003e\u003cp\u003eThe spbk81 is suited for residential and commercial applications involving thin sheet metal work. Common install scenarios include ductwork assembly and connection, HVAC equipment enclosure fastening, electrical panel and conduit support attachment, and light-gauge plumbing bracket work. The bulk pack format supports service vehicles and shop stock where high fastener turnover is expected. The No. 2 driver size is compatible with standard hex-head screw drivers and 1\/4-inch hex bit adapters used across all trades.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSharp piercing point penetrates thin sheet metal without a pilot hole\u003c\/li\u003e\n\u003cli\u003eDWF thread form cuts its own mating threads in light-gauge metal\u003c\/li\u003e\n\u003cli\u003eSlotted hex washer head resists stripping under power-driver use\u003c\/li\u003e\n\u003cli\u003eCarbon steel construction with zinc plated finish for corrosion resistance\u003c\/li\u003e\n\u003cli\u003e15 threads per inch for secure fastening in sheet metal applications\u003c\/li\u003e\n\u003cli\u003eBulk pack format reduces per-unit cost for high-volume trade work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a self-piercing fastener for light-gauge sheet metal applications including HVAC ductwork, plumbing supports, and electrical enclosures.

Ensure the target material is within the rated thickness range for self-piercing screws before driving. De-energize any electrical equipment and depressurize or shut off any plumbing systems before fastening into enclosures or housings. Avoid over-driving, which can strip the formed threads in light-gauge metal.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Sharpeez Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Slotted\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Hex Washer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: DWF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Sharp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 8 x 1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter \/ Thread Size\u003c\/strong\u003e: 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.322 to 0.348 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.096 to 0.110 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 15\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDriver Size\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Carbon Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc Plated\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: LH DOTTIE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: spbk81\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LH DOTTIE","offers":[{"title":"Default Title","offer_id":51268969038130,"sku":"SPBK81","price":355.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308908633.jpg?v=1780711330","url":"https:\/\/voomisupply.com\/products\/lh-dottie-spbk81-8x1-in-metal-piercing-screw-bulk-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
