Manufactured from specially hardened carbon steel, these fasteners provide exceptional tensile, torque, and shear strength, ensuring structural integrity in demanding projects. The patented Climatek™ coating offers superior corrosion resistance, making these screws suitable for use in pressure-treated lumber and intermittent moisture environments. Featuring a unique low-profile washer head, the RSS™ screw provides a massive bearing surface that eliminates the need for separate washers while offering a clean, flush finish.\u003c\/p\u003e\u003cul\u003e  \u003cli\u003e\n\u003cstrong\u003eZip-Tip™ Technology:\u003c\/strong\u003e Pointed tip bites instantly into wood, eliminating the need for pre-drilling and reducing the risk of splitting.\u003c\/li\u003e  \u003cli\u003e\n\u003cstrong\u003eW-Cut™ Thread Design:\u003c\/strong\u003e Reduces installation torque by acting like a saw blade, allowing for faster driving and extended battery life for power tools.\u003c\/li\u003e  \u003cli\u003e\n\u003cstrong\u003eClimatek™ Coating:\u003c\/strong\u003e ICC-ES AC257 certified for high-corrosion environments and ground-contact lumber.\u003c\/li\u003e  \u003cli\u003e\n\u003cstrong\u003eIntegrated Washer Head:\u003c\/strong\u003e Large head diameter provides immense clamping force and centers the screw in pre-drilled hardware.\u003c\/li\u003e  \u003cli\u003e\n\u003cstrong\u003eStar Drive Recess:\u003c\/strong\u003e Features six points of contact for zero stripping and maximum torque transfer.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ctable style=\"width:100%; border-collapse: collapse; margin-top: 20px;\"\u003e  \u003cthead\u003e    \u003ctr style=\"background-color: #f2f2f2;\"\u003e      \u003cth style=\"padding: 10px; border: 1px solid #ddd; text-align: left;\"\u003eTechnical Specification\u003c\/th\u003e      \u003cth style=\"padding: 10px; border: 1px solid #ddd; text-align: left;\"\u003eValue\u003c\/th\u003e    \u003c\/tr\u003e  \u003c\/thead\u003e  \u003ctbody\u003e    \u003ctr\u003e      \u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eDiameter\u003c\/td\u003e      \u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e5\/16\" (8mm)\u003c\/td\u003e    \u003c\/tr\u003e    \u003ctr\u003e      \u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eLength\u003c\/td\u003e      \u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e2-3\/4\" (70mm)\u003c\/td\u003e    \u003c\/tr\u003e    \u003ctr\u003e      \u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eDrive Style\u003c\/td\u003e      \u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eT-30 Star Drive\u003c\/td\u003e    \u003c\/tr\u003e    \u003ctr\u003e      \u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eMaterial\u003c\/td\u003e      \u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eCase-Hardened Carbon Steel\u003c\/td\u003e    \u003c\/tr\u003e    \u003ctr\u003e      \u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eFinish\u003c\/td\u003e      \u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eClimatek™ (Yellow Zinc)\u003c\/td\u003e    \u003c\/tr\u003e    \u003ctr\u003e      \u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eCompliance\u003c\/td\u003e      \u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eICC-ES ESR-2442 Approved\u003c\/td\u003e    \u003c\/tr\u003e    \u003ctr\u003e      \u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eTensile Strength\u003c\/td\u003e      \u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e4,247 lbf\u003c\/td\u003e    \u003c\/tr\u003e  \u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"GRK","offers":[{"title":"Default Title","offer_id":53385101705582,"sku":"GRK-10219","price":299.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0057\/0333\/6025\/files\/Untitled-2026-03-05T113752.190_1.jpg?v=1772691298","url":"https:\/\/wiselinetools.ca\/fr\/products\/grk-grk-10219-rss-rugged-structural-screw-5-16-x-2-3-4-500-pack","provider":"Wise Line Tools","version":"1.0","type":"link"}
