Manufactured from C1022 steel with a hardened body and Type 3 drill point, this screw drives through light-gauge steel framing without a pilot hole. A 1,000-hour Dacro coating provides galvanic corrosion resistance in exterior and moisture-exposed assemblies. The unslotted indented hex washer head with an EPDM bonded washer creates a weather-resistant, load-bearing connection point. Sold in a 250-count pack. This fastener is installed by framing contractors, metal building erectors, and experienced structural trade workers.\u003c\/p\u003e\u003cp\u003eThis screw is suited for light-gauge metal framing, metal purlin attachment, and similar structural metal-to-metal connections found in commercial and residential construction. The self-drilling Type 3 point eliminates pre-drilling steps, reducing installation time on repetitive fastening patterns. The EPDM bonded washer distributes load and provides a seal at the fastener head, making it appropriate for roof panel, wall panel, and framing assemblies where moisture infiltration must be controlled.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSelf-drilling Type 3 point — no pilot hole required for light-gauge steel\u003c\/li\u003e\n\u003cli\u003eC1022 hardened steel construction for consistent drive torque and shear strength\u003c\/li\u003e\n\u003cli\u003e1,000-hour Dacro galvanic coating for corrosion resistance in exterior applications\u003c\/li\u003e\n\u003cli\u003eEPDM bonded washer seals and distributes load at the fastener head\u003c\/li\u003e\n\u003cli\u003eUnslotted indented hex washer head undercut — driven with standard hex bit\u003c\/li\u003e\n\u003cli\u003e250-count pack for production framing and panel work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for metal-to-metal fastening applications including light-gauge steel framing, purlins, and structural panel attachment where a self-drilling hex washer head screw with an EPDM bonded washer is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified framing contractors or sheet metal workers using a hex-drive bit and variable-speed screw gun. Maintain correct RPM to allow the Type 3 drill point to engage cleanly without stripping the head or overdriving the EPDM washer. Follow applicable building code requirements, including IBC fastener schedules and manufacturer-specified fastener spacing for structural assemblies. Do not substitute this fastener in applications requiring stainless steel or a different point type without verifying structural and corrosion requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: #12 x 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: C1022 steel, hardened\u003c\/li\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Dacro, 1,000-hour corrosion resistance\u003cli\u003e\n\u003cstrong\u003eHead Style\u003c\/strong\u003e: Unslotted indented hex washer head undercut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWasher\u003c\/strong\u003e: EPDM bonded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Type 3 self-drilling\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Metal to metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity\u003c\/strong\u003e: 250 per pack\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 4.227 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-MM1212G250\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACORN","offers":[{"title":"Default Title","offer_id":51344151413042,"sku":"SW-MM1212G250","price":47.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310547088.jpg?v=1782030420","url":"https:\/\/voomisupply.com\/products\/acorn-sw-mm1212g250-self-drilling-framing-screw-250-ct","provider":"Voomi Supply","version":"1.0","type":"link"}
