Built to a 2000-hour corrosion-resistance rating, this screw is engineered to reduce common installation problems. A 6-point star drive eliminates cam-out during driving, while serrated threads reduce the torque needed to seat the fastener. Four sharp countersinking blades allow the head to seat flush without pre-drilling a countersink. The knurled shank section helps prevent wood splitting at the fastener zone. Sold in a 5-pound box, this screw is a practical bulk option for high-volume trim work.\u003c\/p\u003e\n\u003cp\u003eThis trim screw is suited for residential and light commercial exterior applications where corrosion resistance and clean head seating matter. Typical uses include installing fiber cement trim, wood trim boards, fascia, and similar finish materials. The sharp point starts without pre-drilling in most trim stock. The coarse thread provides strong holding power in dimensional lumber and engineered wood substrates. This fastener is commonly installed by carpenters, siding contractors, and general construction crews using a drill-driver or impact driver with a T-20 or compatible star bit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2000-hour corrosion resistance rating for exterior use\u003c\/li\u003e\n  \u003cli\u003e6-point star drive system eliminates cam-out\u003c\/li\u003e\n  \u003cli\u003eSerrated threads reduce drive torque during installation\u003c\/li\u003e\n  \u003cli\u003e4 sharp countersinking blades seat the head flush without pre-drilling a countersink\u003c\/li\u003e\n  \u003cli\u003eKnurled shank section reduces wood splitting\u003c\/li\u003e\n  \u003cli\u003eCoarse thread for strong holding power in wood substrates\u003c\/li\u003e\n  \u003cli\u003eSharp point for direct driving into trim stock\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a trim and finish fastener for exterior wood, fiber cement, and engineered wood trim applications requiring a corrosion-resistant, flush-seating screw.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by carpenters and finish contractors using a drill-driver or impact driver fitted with the appropriate star drive bit. Confirm the correct bit size before driving to avoid damaging the drive recess. Although the sharp point reduces the need for pre-drilling in most trim stock, pilot holes are recommended near board ends to minimize splitting risk. Follow applicable building codes for fastener spacing and penetration depth into structural substrates.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 2.5 inches x #8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Coarse, Serrated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: 6-Point Star Drive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Sharp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Style\u003c\/strong\u003e: Countersinking (4-blade)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorrosion Resistance\u003c\/strong\u003e: 2000 hours\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 4 boxes per unit\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 5 pounds per box\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: BX (Box)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: Lifetime Guaranty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 20 pounds (full unit)\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: HILLMAN FASTENERS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 48637\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HILLMAN","offers":[{"title":"Default Title","offer_id":51563286364466,"sku":"48637","price":206.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e7325be7738bcfcf6ecfc65e40bce112_b84f67e9-4e6b-4a88-9527-cebd456a511d.jpg?v=1786494715","url":"https:\/\/voomisupply.com\/products\/hillman-fasteners-48637-star-drive-trim-screw-2-5x8-5lb","provider":"Voomi Supply","version":"1.0","type":"link"}
