Countersunk Head Wood Screws
Product Overview
This product is a specialised wood screw, manufactured from SS304 stainless steel, with lengths ranging from 19‑42mm. Featuring a countersunk head with ribs, a #2 square recess drive, and deep coarse wood threads, it combines the three key advantages of rust resistance, easy installation, and high fastening strength. Suitable for indoor humid environments and general outdoor wooden structures, it is a premium fastener choice for mid‑to‑high‑end woodworking applications.
Product Applications
Interior Furnishings: Custom cabinetry for whole‑house solutions, solid wood furniture, skirting boards, wooden ceilings, moisture‑resistant wooden components in kitchens and bathrooms, etc.
Outdoor Landscaping: Preservative‑treated timber decks, boardwalks, fences, garden trellises, and balcony wooden furniture.
Compatible Materials: Suitable for various softwoods and hardwoods, plywood, medium‑density fibreboard (MDF), particleboard, and thermally modified preservative‑treated timber.
Application Scenarios: Ideal for DIY home installations, mass production in furniture factories, wooden handicrafts, and small‑to‑medium‑sized timber structure projects.
Product Features
SS304 Stainless Steel Material: Provides inherent rust and corrosion resistance, ensuring it does not rust easily in humid conditions and will not stain wood finishes. Its service life outperforms carbon steel and zinc‑plated screws.
Countersunk Head with Ribs Design: Allows the screw head to be fully embedded into the workpiece for a smooth, flush surface. The ribs automatically ream the hole during driving, effectively preventing edge chipping and splitting in dense board and hardwoods, while eliminating the need for pre‑countersinking.
#2 Square Recess Drive: Ensures even force distribution, reducing the risk of stripping or bit jumping during power‑tool operation. Capable of handling high torque, it is ideal for batch furniture production and offers durable performance with low wear over repeated use.
Deep Coarse Wood Threads: Bite deeply into wood fibres for strong pull‑out resistance, maintaining joint integrity even under temperature and humidity fluctuations.
Complete Size Range: Available in lengths from 19‑42mm, covering the majority of woodworking assembly requirements.
