Made of specially hardened steel, these screws provide industry-leading tensile, torque, and shear strength. The patented W-Cut design and Zip-Tip point allow for rapid penetration without the need for pre-drilling, significantly reducing installation time and physical effort on the job site.\u003c\/p\u003e\u003cp\u003eEquipped with an integrated washer-type head, the RSS screw offers immense holding power and a low-profile finish with no sharp edges. For lengths 3-1\/8 inches and longer, the CEE Thread feature enlarges the screw hole for the non-threaded shank, allowing the wood to settle naturally while increasing drawing strength and reducing friction. The Climatek coating provides superior corrosion resistance, making these fasteners code-approved for use in pressure-treated lumber.\u003c\/p\u003e\u003cul\u003e  \u003cli\u003e\n\u003cstrong\u003eClimatek Coating:\u003c\/strong\u003e AC257 code-approved for use in treated lumber and harsh environments.\u003c\/li\u003e  \u003cli\u003e\n\u003cstrong\u003eZip-Tip Technology:\u003c\/strong\u003e Precision point for fast starts and immediate biting without pre-drilling.\u003c\/li\u003e  \u003cli\u003e\n\u003cstrong\u003eCEE Thread:\u003c\/strong\u003e Enlarges the hole to reduce driving torque and prevent wood splitting.\u003c\/li\u003e  \u003cli\u003e\n\u003cstrong\u003eStar Drive Recess:\u003c\/strong\u003e T-30 drive size provides six points of contact to eliminate stripping.\u003c\/li\u003e  \u003cli\u003e\n\u003cstrong\u003eWasher Head:\u003c\/strong\u003e Built-in shield head centers the screw and provides massive drawing power.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ctable\u003e  \u003ccaption\u003eTechnical Specifications\u003c\/caption\u003e  \u003ctbody\u003e    \u003ctr\u003e      \u003cth\u003eSeries\u003c\/th\u003e      \u003ctd\u003eRSS (Rugged Structural Screw)\u003c\/td\u003e    \u003c\/tr\u003e    \u003ctr\u003e      \u003cth\u003eScrew Diameter\u003c\/th\u003e      \u003ctd\u003e5\/16\"\u003c\/td\u003e    \u003c\/tr\u003e    \u003ctr\u003e      \u003cth\u003eLength\u003c\/th\u003e      \u003ctd\u003e5-1\/8\"\u003c\/td\u003e    \u003c\/tr\u003e    \u003ctr\u003e      \u003cth\u003eDrive Type\u003c\/th\u003e      \u003ctd\u003eT-30 Star Drive\u003c\/td\u003e    \u003c\/tr\u003e    \u003ctr\u003e      \u003cth\u003eMaterial\u003c\/th\u003e      \u003ctd\u003eCase Hardened Steel\u003c\/td\u003e    \u003c\/tr\u003e    \u003ctr\u003e      \u003cth\u003eFinish\u003c\/th\u003e      \u003ctd\u003eClimatek Corrosion Resistant Coating\u003c\/td\u003e    \u003c\/tr\u003e    \u003ctr\u003e      \u003cth\u003eHead Type\u003c\/th\u003e      \u003ctd\u003eWasher Head\u003c\/td\u003e    \u003c\/tr\u003e    \u003ctr\u003e      \u003cth\u003eThread Style\u003c\/th\u003e      \u003ctd\u003ePartially Threaded with CEE Thread\u003c\/td\u003e    \u003c\/tr\u003e  \u003c\/tbody\u003e\n\u003c\/table\u003e\u003cp\u003e\u003cstrong\u003eWhat's Included:\u003c\/strong\u003e (300) 5\/16\" x 5-1\/8\" RSS Structural Screws in a bulk contractor box.\u003c\/p\u003e","brand":"GRK","offers":[{"title":"Default Title","offer_id":53385101967726,"sku":"GRK-10231","price":319.0,"currency_code":"CAD","in_stock":false}],"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-10231-rss-structural-screws-5-16-in-x-5-1-8-in-300-pack","provider":"Wise Line Tools","version":"1.0","type":"link"}
