Product Overview
This product, specification 14‑7×50‑150, is integrally manufactured from SS316 (A4) austenitic stainless steel, making it a heavy‑duty anti‑corrosion self‑tapping screw specifically for outdoor timber structures. It features a Torx drive recess, double countersunk head, two‑stage thread, and a square cutting point, with lengths covering 50‑150 mm. The material contains molybdenum, offering resistance to salt spray, acids, and alkalis. Combined with the optimised design, it effectively solves common issues such as splitting of thick timber, gap formation at joints, driver stripping during installation, and outdoor rusting. It is suitable for timber projects requiring high corrosion resistance and long‑term durability.
