Countersunk Head Wood Screws
Product Overview
This product is a 304 stainless steel wood screw with lengths of 50‑65mm, featuring a twisted cutting shank combined with coarse‑pitch quick‑thread geometry, and a double countersunk Torx recess structure. It is a premium fastening accessory suitable for thick solid wood and preservative‑treated timber. Made entirely of stainless steel without coating, it eliminates the risk of peeling and combines efficient installation with long‑term rust resistance, making it ideal for long‑term fixation in indoor damp areas and outdoor wooden structures.
Product Applications
Interior Furnishings: Solid wood flooring, timber joists, custom cabinetry for whole‑house solutions, moisture‑resistant wooden components in kitchens and bathrooms, and wall panelling.
Furniture: Solid wood tables and chairs, staircases, children's pine furniture, and rustic wood crafts.
Outdoor Projects: Preservative‑treated timber decks, courtyard fences, wooden boardwalks, timber cabins, and outdoor planter boxes.
Product Features
SS304 Stainless Steel Substrate: Resists moisture corrosion and does not rust easily in outdoor or humid environments. It will not stain wood or cause black rust marks.
Double Countersunk Head with Cutting Teeth: Allows the screw head to be fully embedded into the board for a flush surface. It disperses stress in the wood, effectively reducing splitting and edge chipping.
Torx Star Recess: Provides even force distribution and high torque without cam‑out, suitable for batch installation with power drills, resulting in lower screw wear.
Twisted Cutting Shank: Enables pre‑drilling to be omitted in softwoods. The rotating action cuts through wood fibres and evacuates chips smoothly, allowing faster driving speeds.
Deep, Coarse, and Extended Threads: With an extended 50‑65mm shank providing substantial thread engagement, it offers high pull‑out strength, ensuring that thick timber joists and panels remain securely fastened without loosening.
