Manufactured from heat-treated C1022 steel with a case-hardened finish, 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 and maintains a long-lasting seal. The twin lead Type 17 point combined with hi-lo threads reduces drive time and increases pull-out resistance. A dacro base coating provides 1,000-hour salt spray protection, with a white powder coat applied over the dacro for color-matched installations. Sold in a pack of 250 screws.\u003c\/p\u003e\u003cp\u003eThese metal-to-wood screws are intended for attaching metal panels, roofing sheets, or siding to wood substrates in both residential and light commercial construction. The self-piercing tip eliminates the need for pre-drilling in most standard applications, making them a practical choice for roofing contractors and siding installers working with steel or aluminum cladding over wood framing or sheathing. The EPDM washer assembly is critical in applications exposed to weather, providing a compressed seal at each fastener point to prevent water infiltration.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSelf-piercing Type 17 point eliminates pre-drilling in standard applications\u003c\/li\u003e\n\u003cli\u003eHeat-treated C1022 steel construction, case-hardened for durability\u003c\/li\u003e\n\u003cli\u003e1\/4-inch across-flat high-hat hex washer head for easy driving with standard hex drivers\u003c\/li\u003e\n\u003cli\u003eAssembled EPDM washer conforms to surface for a weathertight seal\u003c\/li\u003e\n\u003cli\u003eHi-lo threads provide faster drive time and greater pull-out resistance\u003c\/li\u003e\n\u003cli\u003e1,000-hour salt spray rated dacro coating with white powder coat over-finish\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for metal-to-wood fastening in roofing and siding applications, compatible with steel and aluminum panel systems installed over wood framing or structural sheathing.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed with a standard hex driver bit sized for 1\/4-inch hex heads; use a variable-speed drill or screw gun to avoid over-driving and compressing the EPDM washer beyond its sealing range. Follow applicable building codes and manufacturer panel installation guidelines for fastener spacing and edge distance. Inspect each installed screw to confirm the washer is seated flush against the panel surface without excessive deformation.\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\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\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\u003c\/strong\u003e: Assembled EPDM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Dacro base coat with white powder coat over-finish\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSalt Spray Rating\u003c\/strong\u003e: 1,000 hours\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePack Quantity\u003c\/strong\u003e: 250 pieces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 3.227 pounds\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-MW2W250\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACORN","offers":[{"title":"Default Title","offer_id":51346808734002,"sku":"SW-MW2W250","price":44.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310547114.jpg?v=1782091096","url":"https:\/\/voomisupply.com\/products\/acorn-sw-mw2w250-metal-to-wood-screw-white-250-ct","provider":"Voomi Supply","version":"1.0","type":"link"}
