Product Overview
SS316 Double Countersunk Torx Drive Two‑Thread Square Cone Wood Screw is a professional‑grade fastener specifically designed for timber structure connections in highly corrosive environments. It is integrally formed from A4 grade 316 stainless steel, with a shank diameter of approximately 7 mm (#14 gauge), and lengths ranging from 50 to 150 mm. Featuring a Torx drive recess, double countersunk head, two‑stage thread design, and a square cutting point, it is specifically designed for outdoor preservative‑treated timber, landscape engineering, and coastal timber structures. It combines high strength, superior corrosion resistance, and easy installation, making it an upgraded choice over conventional carbon steel and 304 stainless steel screws.
Product Applications
Outdoor Landscaping and Preservative‑Treated Timber Projects: Widely used in preservative‑treated timber decking, terrace boardwalks, outdoor pavilions, wooden fences, planter boxes, and other scenarios, withstanding sun, rain, and humid conditions. Long‑term use ensures no rusting or loosening, guaranteeing the stability and safety of timber structures.
Timber Structures in Coastal and Highly Corrosive Environments: Suitable for seaside docks, coastal boardwalks, seaside landscape cabins, and other areas with high chloride ion concentrations. The salt‑spray corrosion resistance of 316 stainless steel effectively prevents structural failure caused by screw rusting and fracture.
Humid Indoor and Special Scenarios: Also applicable to bathroom wooden cabinets, sauna timber components, marine wooden parts, and other applications with prolonged exposure to moisture, as well as high‑end woodworking and furniture making that demand superior rust protection and strength.
