It is engineered to fasten steel roofing panels directly to wood substrates without pre-drilling. The hex washer head (HWH) features a V-neck design that adds clamping strength and resists head pop-out under load. The coating system applies 2.5 mils of powder with a chromate sealer for enhanced corrosion resistance beyond standard painted-head fasteners. A built-in EPDM rubber washer is vulcanized to a steel backing washer, forming a weather-tight seal even when the screw is driven slightly off-angle. A Pro-Stick bit is included.\u003c\/p\u003e\u003cp\u003eThis screw is intended for post-frame construction where steel roofing panels are fastened to wood purlins, and for residential applications where steel roofing is applied over plywood or OSB decking. The thread design transitions from fine to coarse along the shank, generating holding strength across varying wood densities and substrates. The micro-bit point minimizes metal shavings during drilling, reducing the risk of debris embedding in the EPDM washer and compromising the seal. Licensed contractors and experienced roofers working on both agricultural and residential steel-roof systems are the primary installers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSelf-drilling point eliminates pre-drilling in metal-to-wood applications\u003c\/li\u003e\n\u003cli\u003e2.5 mils powder coat with chromate sealer for enhanced corrosion resistance\u003c\/li\u003e\n\u003cli\u003eEPDM rubber vulcanized to steel washer forms a weather-tight seal at angle\u003c\/li\u003e\n\u003cli\u003eHWH V-neck design increases head strength and prevents pop-out\u003c\/li\u003e\n\u003cli\u003eFine-to-coarse thread transition improves holding strength in wood substrates\u003c\/li\u003e\n\u003cli\u003eMicro-bit point reduces metal shavings near the rubber washer\u003c\/li\u003e\n\u003cli\u003ePro-Stick drive bit included in each pack\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for fastening steel roofing panels to wood purlins in post-frame construction and to plywood or OSB decking in residential construction.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by roofing contractors or general contractors experienced with metal panel systems. Drive with a variable-speed drill or impact driver set to a controlled clutch setting to avoid over-driving and compressing the EPDM washer beyond its design limit. Ensure the substrate is clean and dry before fastening. Follow applicable building codes and manufacturer panel specifications for fastener spacing and edge distances.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 10 x 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Red powder coat with chromate sealer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Thickness\u003c\/strong\u003e: 2.5 mils\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWasher Material\u003c\/strong\u003e: EPDM rubber vulcanized to steel washer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Style\u003c\/strong\u003e: Hex washer head (HWH) with V-neck design\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Self-drilling micro-bit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Metal to wood\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.7 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: HILLMAN FASTENERS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 117920\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HILLMAN","offers":[{"title":"Default Title","offer_id":51559818658098,"sku":"117920","price":76.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2871470f44d242107d142a3712bab50a_583bd87f-172a-4f03-9f0f-dd201cbe5697.jpg?v=1786441910","url":"https:\/\/voomisupply.com\/products\/hillman-fasteners-117920-roofing-screw-10x1-5-red-5-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
