Manufactured from pickled, passivated, and lubricated A2 stainless steel, these screws feature a long drill tip and specialized reaming wings that reduce screw-in resistance and drilling stress while preventing the wood from splitting. The single-start partial thread ensures a high load-bearing capacity, providing a secure and durable hold for demanding façade cladding projects.\n\nFor a professional and efficient finish, the screw is equipped with a small countersunk head featuring integrated milling ribs, which allow for flush countersinking without the need for pre-drilling or pre-countersinking. The SIT® 20 drive system enables quick access and maximum power transmission with no tumbling motion, though it remains fully compatible with standard TX bits for added convenience on-site.","brand":"Certifix","offers":[{"title":"Default Title","offer_id":51216761913508,"sku":"17749","price":214.58,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0657\/4496\/1700\/files\/00SID1V011-0500451-1_G_0f81ec36.jpg?v=1769225277","url":"https:\/\/certifix.co.uk\/products\/siding-wing-type-drilling-screw-countersunk-head-5-0-x-45-partial-thread-l1-sit%c2%ae-20-stainless-steel-a2-pickled-passivated-lubricated-500-pcs","provider":"Certifix","version":"1.0","type":"link"}
