Manufactured from heat-treated C1022 steel with case hardening, each screw features a 1\/4-inch across-flat high-hat hex washer head with an assembled EPDM (Ethylene Propylene Diene Monomer) washer that conforms to the substrate surface for a secure, lasting seal. The twin-lead Type 17 point and hi-lo thread profile deliver faster drive times and higher pull-out resistance compared to standard thread designs. All screws carry a dacro base coating rated for 1,000-hour salt spray resistance, with white powder coat applied over the dacro layer.\u003c\/p\u003e\u003cp\u003eThese screws are suited for residential and light commercial roofing and siding installations where a weather-resistant, self-sealing metal-to-wood connection is required. The EPDM washer compresses against the panel or sheet material on installation, creating a seal that resists moisture intrusion at the fastener point. The hi-lo thread geometry reduces driving torque, making these screws practical for production installations where speed and consistency matter. Each pack contains 250 screws sold as a single unit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSelf-piercing Type 17 point drives without a pilot hole in sheet metal-to-wood applications\u003c\/li\u003e\n\u003cli\u003eHi-lo thread profile increases pull-out resistance and reduces drive torque\u003c\/li\u003e\n\u003cli\u003eAssembled EPDM washer seals the fastener penetration point against moisture\u003c\/li\u003e\n\u003cli\u003e1\/4-inch across-flat hex washer head for standard hex driver bits\u003c\/li\u003e\n\u003cli\u003e1,000-hour salt spray rated dacro base coating for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eWhite powder coat finish over dacro base for color-matched panel installations\u003c\/li\u003e\n\u003cli\u003e250 screws per pack\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for metal-to-wood fastening in roofing and siding applications where a self-sealing, self-piercing screw with an EPDM washer is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by roofing or siding contractors using a hex-head screw gun or drill driver fitted with a 1\/4-inch hex bit and adjustable depth-sensitive nosepiece. Drive to the point where the EPDM washer is compressed flush against the panel surface without over-driving, which can compromise the seal. Follow applicable building codes and manufacturer panel guidelines for fastener spacing and edge distances. Do not mix fastener types within a single panel run where uniform corrosion resistance is required.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Heat-treated C1022 steel, case hardened\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Style\u003c\/strong\u003e: High-hat hex washer head\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Size\u003c\/strong\u003e: 1\/4 inch across flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWasher\u003c\/strong\u003e: Assembled EPDM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Twin-lead hi-lo\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Type 17 self-piercing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Dacro base with white powder coat topcoat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorrosion Rating\u003c\/strong\u003e: 1,000-hour salt spray tested\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity\u003c\/strong\u003e: 250 pieces per pack\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.56 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00810468002849\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACORN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SW-MW15W250\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACORN","offers":[{"title":"Default Title","offer_id":51344150364466,"sku":"SW-MW15W250","price":39.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310547060.jpg?v=1782030385","url":"https:\/\/voomisupply.com\/products\/acorn-sw-mw15w250-metal-to-wood-screw-white-250-count","provider":"Voomi Supply","version":"1.0","type":"link"}
