Timco C2 Deck-Fix Premium Decking Screws, 4.5x75mm, Green, 120-Pack
Premium green decking screws with twin-cut tech & 1,000hr corrosion resistance. TX20 drive, 4.5x75mm, 120pc.
The Timco C2 Deck-Fix Premium Decking Screws combine advanced engineering with superior corrosion resistance for long-lasting outdoor performance. Featuring patented twin-cut technology, these screws minimise timber splitting while enabling rapid penetration and clean countersinking for efficient decking installations. A multi-layer corrosion-resistant plating ensures exceptional durability, withstanding up to 1,000 hours in salt spray testing—ideal for coastal or high-moisture environments.
The screws’ helix shank removes debris during installation, improving clamping force between decking boards and joists. Reinforced heads prevent shearing under high torque, while ribs under the head ensure consistent countersinking. The TX20 drive system offers better grip and reduced cam-out compared to standard star drives.
