Carbon Steel Wood Screws
Product Overview
This 8–10×25–45 series Zinc‑Nickel Alloy Double Countersunk Torx Drive Fast‑Thread Wood Screw is a high‑performance fastening solution designed specifically for wood‑connection applications. Manufactured from high‑strength steel substrate with a B8‑grade zinc‑nickel alloy surface treatment, combined with an optimized fast‑thread geometry and Torx drive design, it delivers efficient installation, crack‑resistance, and extended corrosion protection. It is widely suitable for both indoor and outdoor timber structures, particularly meeting the long‑term service requirements in harsh environments such as high humidity and high salt spray.
Product Applications
Installation of indoor and outdoor wood flooring, preservative‑treated wood decks, and terrace boardwalks;
Wood‑to‑wood and steel‑to‑wood connections in solid wood furniture, wooden house frames, timber joists, and other timber structures;
Splicing and fixing of OSB, multi‑layer composite boards, and other engineered panels;
Timber construction projects with high anti‑corrosion requirements, such as those in humid environments and coastal areas.
Product Features
Fast‑thread & crack‑prevention for efficient installation: The large‑lead fast‑thread profile incorporates cutting edges, enabling rapid driving into wood without pre‑drilling; the double countersunk head can be fully recessed into the wood, suppressing fibre splitting while ensuring installation efficiency and a neat surface finish.
Torx drive for non‑slip, cam‑out free driving: The internal Torx recess engages tightly with the driver bit, capable of withstanding high tightening torque and suitable for power‑tool batch installation, significantly reducing bit wear and slipping.
Zinc‑nickel coating for superior corrosion resistance: The zinc‑nickel alloy plating withstands salt spray tests for 500‑1000 hours, offering far better corrosion resistance than conventional zinc plating; it is compatible with preservative‑treated wood and performs well in harsh outdoor, humid, and coastal high‑salt environments.
Comprehensive size range for broad adaptability: Available in multiple diameters and lengths, with a partial‑thread design that quickly pulls multiple layers of panels together, meeting various fastening needs for different wood thicknesses and splicing applications.
