Stainless Steel Wood Screws
Product Overview
This product is an SS316 (A4 grade) stainless steel Torx small countersunk head nail point wood screw, specifically designed for timber structure connections in outdoor and highly corrosive environments. Available in 10G (approx. 4.8 mm) diameter and lengths from 50 mm to 65 mm, it features a T20 Torx drive head, combined with a self‑tapping sharp point and cutting flutes. It is an ideal fastener for preservative‑treated timber decking, terrace boardwalks, landscape engineering, and similar applications.
Product Applications
Outdoor Preservative‑Treated Timber Projects: Fixing planks on preservative‑treated timber decking, terraces, boardwalks, and timber platforms, suitable for outdoor panels with thicknesses of 19‑25 mm.
Landscape and Garden Structures: Installation of timber components such as cabins, pavilions, fences, trellises, and outdoor tables and chairs.
Coastal and High‑Humidity Environments: Timber structure connections in areas with severe salt‑spray corrosion, such as docks, seaside boardwalks, and island landscapes.
Marine and Offshore Facilities: Fastening timber components on small boats, floating platforms, etc., meeting marine‑grade corrosion protection requirements.
Product Features
Marine‑Grade Corrosion Resistance: SS316 (A4 grade) stainless steel offers excellent resistance to salt spray, acids, and alkalis, ensuring long‑term outdoor use without rusting or fracture in coastal and humid environments.
Efficient and Split‑Resistant: The self‑tapping sharp point with cutting flutes allows easy driving into wood without pre‑drilling, significantly reducing the risk of splitting in hardwoods and making installation more effortless.
Secure and Aesthetic: The T20 Torx recess ensures even torque transmission, preventing slippage and stripping; the small countersunk head embeds completely flush with the wood surface after installation, leaving a smooth, snag‑free finish.
Strong Pull‑Out Resistance and Anti‑Loosening: The matched thread profile, combined with the high‑toughness stainless steel material, provides tight engagement, resisting loosening caused by vibration or thermal expansion/contraction over long‑term use.
