Countersunk Head Wood Screws
Product Overview
The Square Recess Countersunk Stainless Steel Wood Screw (Specification 5.0×75) is a high‑performance fastener specifically designed for wood connections. With a nominal diameter of 5.0mm and a total length of 75mm, it is manufactured from stainless steel, offering excellent rust and corrosion resistance along with reliable mechanical strength. The countersunk tapered head, combined with the square recess drive system, ensures a flush installation while significantly improving driving efficiency and resistance to cam‑out. This screw is an ideal choice for outdoor wooden structures, indoor furniture, and projects in humid environments.
Product Applications
Outdoor Wood Structures: Ideal for preservative‑treated timber decks, garden fences, patio walkways, outdoor pergolas, etc. The stainless steel construction withstands rain and sun exposure, ensuring stable performance over time.
Furniture & Interior Decoration: Suitable for solid wood furniture, floor joists, wall panelling, cabinets, and more. The countersunk design guarantees a smooth, level surface, while the square recess drive enables efficient installation across various woodworking scenarios.
Humid & Special Environments: Perfect for bathroom vanities, kitchen cabinets, poolside facilities, etc., where moisture resistance and anti‑rust performance are critical – preventing the staining and structural issues caused by corroded ordinary screws.
General Wood Connections: Used for joining thick planks, multi‑layer boards, and wooden structural frames, offering a balanced solution for applications requiring strength, aesthetics, and long‑term durability.
Product Features
Stainless Steel Material: Resists moisture, salt spray, and corrosion, ensuring long‑term service without rusting – far outlasting ordinary carbon steel screws.
Square Recess Drive: Provides a large contact area with the matching bit, enabling efficient torque transmission, reducing slippage and stripping during installation, and offering strong resistance to cam‑out.
Countersunk Head Design: Sits fully below the workpiece surface after driving, achieving a flush finish that combines secure fastening with aesthetic appeal.
Self‑tapping Wood Thread: Features a sharp pointed tip and deep thread profile, allowing direct drilling into wood without pre‑tapping, delivering high holding power and minimising the risk of wood splitting.
