The drill point eliminates the need for pre-drilled holes, allowing the screw to penetrate and tap its own mating thread in a single operation. A factory-installed neoprene washer under the head creates a water-tight seal at the fastener point and acts as a corrosion buffer between dissimilar surfaces. Each screw measures 12-14 by 1.5 inches and the package contains 100 pieces. Zinc construction provides baseline corrosion resistance. These are a standard choice for licensed roofers, sheet metal mechanics, and general contractors working with metal panel systems.\u003c\/p\u003e\u003cp\u003eThis screw is suited for residential and light commercial roofing panels, metal-to-wood substrate connections, fiberglass panel attachment, and thin-gauge sheet metal assembly. The self-drilling tip reduces installation time on production roofing work where pre-drilling would add significant labor. The neoprene washer seal makes it particularly appropriate for exposed fastener metal roof systems where weather infiltration at the fastener is a primary concern.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSelf-drilling tip penetrates thin-gauge steel without pre-drilling\u003c\/li\u003e\n\u003cli\u003eSharp threads form their own mating thread for a secure mechanical grip\u003c\/li\u003e\n\u003cli\u003eNeoprene washer under the head provides a water-tight seal\u003c\/li\u003e\n\u003cli\u003eNeoprene barrier reduces galvanic corrosion between contact surfaces\u003c\/li\u003e\n\u003cli\u003eZinc construction for baseline corrosion resistance\u003c\/li\u003e\n\u003cli\u003e100 screws per box for production-quantity roofing work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in wood, fiberglass, and thin-gauge sheet metal substrates; well-suited as a standard exposed-fastener roofing screw for metal panel roof systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by licensed roofers or sheet metal mechanics using a variable-speed drill driver with a hex-head bit. Apply consistent, controlled drive pressure to avoid overdriving and compressing the neoprene washer beyond its effective sealing range. Disconnect or lock out any powered equipment in the work area before working near live electrical components on a rooftop. Follow applicable local building codes and manufacturer panel specifications for fastener spacing and edge distance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: 12-14 x 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Zinc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWasher Type\u003c\/strong\u003e: Neoprene\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 100 pieces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 3.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Box\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HILLMAN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 561042\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HILLMAN","offers":[{"title":"Default Title","offer_id":51345227579698,"sku":"561042","price":57.07,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310549167.jpg?v=1782052146","url":"https:\/\/voomisupply.com\/products\/hillman-561042-washer-head-self-drilling-screw-100-ct","provider":"Voomi Supply","version":"1.0","type":"link"}
