Product Overview
The SS316 Torx Double Countersunk Two-Stage Thread Square Cone Wood Screw is a professional-grade fastener specifically designed for wood structure connections in highly corrosive environments. Manufactured from A4-grade 316 stainless steel in one-piece construction, with a shank diameter of approximately 7mm (#14 gauge) and lengths ranging from 50–150mm, it features a Torx drive, double countersunk head, two-stage thread, and a square cutting point. Engineered specifically for outdoor treated wood, landscape projects, and coastal timber structures, it combines high strength, superior corrosion resistance, and ease of installation, making it a premium upgrade over ordinary carbon steel or 304 stainless steel screws.
Product Applications
Outdoor landscaping and treated-wood projects: Widely used for treated-wood flooring, decking, and boardwalks, outdoor pavilions, wooden fencing, planter boxes, and similar applications. Withstands sun, rain, and humid conditions, maintaining rust-free and loosening-free performance over the long term, ensuring the stability and safety of timber structures.
Coastal and highly corrosive timber structures: Suited for seaside docks, coastal boardwalks, seaside landscape cabins, and other environments with high chloride ion concentrations. The salt-spray corrosion resistance of 316 stainless steel effectively prevents structural failures caused by screw rusting and breakage.
Humid indoor and special applications: Also suitable for bathroom wooden cabinets, sauna timber components, marine wood parts, and other scenarios with prolonged moisture exposure, as well as high-end woodworking and furniture-making applications that demand superior rust protection and strength.
