Made from C1022 steel with case hardening, these screws feature a 3-point drill tip that penetrates up to 0.25 inches of metal. Reamer wings bore cleanly through the wood layer and snap off automatically when they contact metal, allowing the screw to seat flush. A shank slot captures steel shavings and improves drilling action throughout the drive cycle. All screws carry a dacro coating rated to 1,000 hours of salt spray exposure for corrosion resistance in harsh environments.\u003c\/p\u003e\n\u003cp\u003eThese screws are sized at 2.5 inches in length and are designed for applications where wood panels or framing meet a steel or aluminum substrate. Typical install scenarios include trailer beds, trailer walls, and similar light structural assemblies where a clean, one-step fastening process is required. The star drive flat head configuration reduces cam-out, handles greater torque than Phillips or square drive heads, and eliminates fastener spinning during installation. A T30 driver bit is required and is not included in the pack. Each pack contains 250 screws.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eC1022 steel construction with case hardening for durability and shear strength\u003c\/li\u003e\n  \u003cli\u003e3-point drill tip penetrates up to 0.25 inches of metal with no predrilling required\u003c\/li\u003e\n  \u003cli\u003eReamer wings drill through wood and snap off automatically at the metal surface\u003c\/li\u003e\n  \u003cli\u003eShank slot retains steel shavings and maintains clean drilling action\u003c\/li\u003e\n  \u003cli\u003eStar drive flat head reduces cam-out and handles higher torque than Phillips or square drive\u003c\/li\u003e\n  \u003cli\u003eDacro coating rated to 1,000 hours salt spray resistance for corrosion protection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for fastening wood to steel or aluminum substrates up to 0.25 inches thick.

Use a T30 star drive bit sized for the fastener head. No pilot hole is required in the metal substrate. Allow the reamer wings to clear the wood layer fully before the screw contacts metal so the wings snap off cleanly and the shank seats properly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: C1022 Steel, Case Hardened\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Star Drive (T30), Flat Head\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point\u003c\/strong\u003e: 3-Point Self-Drilling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMax Metal Penetration\u003c\/strong\u003e: 0.25 inches (no predrilling)\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\u003eSubstrate\u003c\/strong\u003e: Wood to Steel or Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity per Pack\u003c\/strong\u003e: 250\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePack Weight\u003c\/strong\u003e: 5.213 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00810468001484\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: S-WM12212G250\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACORN","offers":[{"title":"Default Title","offer_id":51343074656562,"sku":"S-WM12212G250","price":61.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310547089.jpg?v=1782015766","url":"https:\/\/voomisupply.com\/products\/acorn-s-wm12212g250-self-drilling-screw-250-count","provider":"Voomi Supply","version":"1.0","type":"link"}
