Wood Screws – Carbon Steel – Indoor & Outdoor Use

Product Overview

Our 3.5 × 25mm high-performance wood screws are expertly designed for fast insertion and robust holding power in hardwood, softwood, and sheet materials. Crafted from hardened steel with a corrosion-resistant plated finish, they ensure smooth driving, controlled torque, and long-term reliability. The countersunk head provides a clean, flush seating, while the twin-cut thread design reduces splitting and ensures rapid cutting in dense timber. The 3.5 × 25mm size is perfect for trims, beading, and panel work where shallow penetration and a neat finish are required.
