Manufactured from heat-treated C1022 steel with a case-hardened finish, the screw measures 1-1\/2 inches in length and features a 1\/4-inch across-flat high-hat hex washer head with an assembled EPDM (Ethylene Propylene Diene Monomer) washer. The EPDM washer conforms to the mating surface under torque, creating a durable, long-lasting seal. A twin-lead Type 17 point combined with hi-lo threads reduces drive time and increases pullout resistance. Each screw carries a dacro coating that has passed a 1,000-hour salt spray test. This pack contains 250 screws.\u003c\/p\u003e\u003cp\u003eThese metal-to-wood screws are suited for attaching metal roofing panels, metal siding, and similar sheet-metal cladding directly to wood structural members. The self-piercing Type 17 point eliminates the need for a pilot hole through the metal layer, speeding up installation on residential and light commercial projects. The hex washer head accepts a standard 1\/4-inch hex driver bit. Color options feature an additional powder coat applied over the dacro base for finish-matched installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSelf-piercing Type 17 point eliminates pilot drilling through metal\u003c\/li\u003e\n\u003cli\u003eTwin-lead hi-lo threads for faster drive time and higher pullout resistance\u003c\/li\u003e\n\u003cli\u003eAssembled EPDM washer seals against moisture intrusion at the fastener point\u003c\/li\u003e\n\u003cli\u003e1\/4-inch across-flat high-hat hex washer head for standard hex driver compatibility\u003c\/li\u003e\n\u003cli\u003eDacro coating rated to 1,000 hours salt spray for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eHeat-treated, case-hardened C1022 steel construction\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for metal-to-wood fastening applications including metal roofing and metal siding panels attached to wood framing or sheathing.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by roofing or siding contractors using a variable-speed screw gun fitted with a 1\/4-inch hex drive bit and a depth-sensitive nosepiece to prevent over-driving and EPDM washer deformation. Fasten only to dry, structurally sound wood substrate. Follow applicable building codes and manufacturer panel guidelines for fastener spacing and edge distance. Over-driving will compress the EPDM washer excessively and compromise the seal.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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\u003eHex Size\u003c\/strong\u003e: 1\/4 inch across flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Twin-lead Type 17\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Hi-lo\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWasher Material\u003c\/strong\u003e: EPDM (Ethylene Propylene Diene Monomer)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase Material\u003c\/strong\u003e: Heat-treated C1022 steel, case hardened\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Dacro, 1,000-hour salt spray rated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePack Quantity\u003c\/strong\u003e: 250 pieces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePack Weight\u003c\/strong\u003e: 2.565 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00810468002832\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-MW15LS250\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACORN","offers":[{"title":"Default Title","offer_id":51347549880626,"sku":"SW-MW15LS250","price":38.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310547063.jpg?v=1782108244","url":"https:\/\/voomisupply.com\/products\/acorn-sw-mw15ls250-metal-to-wood-screw-250-count","provider":"Voomi Supply","version":"1.0","type":"link"}
