Timco C2 Strong-Fix Screws

About Timco C2 Strong-Fix Screws

Timco C2 Strong-Fix Screws are high-strength woodscrews developed for demanding timber applications where reliable hold, clean installation and consistent drive performance are essential.

They’re designed for professional use across structural timber work, offering a noticeable step up from general-purpose woodscrews in terms of drive control, pull-out resistance and installation efficiency. This makes them a trusted choice for site work where speed and repeatable results matter.

Designed for Structural Timber Fixing

C2 Strong-Fix Screws are commonly used in applications where strength and holding power are critical, including:

• Decking and external timber structures
• Fencing and gate construction
• Joists and floor construction
• Timber framing
• General structural timber fixing

They’re suitable for both softwood and hardwood, and are designed to perform reliably in repetitive fixing tasks without compromising finish or control.

Key Performance Features

C2 Strong-Fix Screws incorporate advanced design features to improve performance during installation and long-term fixing strength:

Precise drive with reduced cam-out

A deep Pozi recess provides positive drive engagement, helping prevent cam-out and improving control during installation. This allows for accurate driving and consistent results, particularly when working at speed.

Clean countersinking with reduced splitting

Ribs under the head improve countersinking, allowing the screw to sit flush while helping to reduce timber splitting and surface damage - especially when fixing close to edges.

Faster driving with less torque

Each screw is coated with a high-molecular polymer lubricant, reducing insertion torque by up to 52%. This enables faster driving, reduces strain on tools, and improves efficiency on longer fixing runs. The coating also offers significantly increased corrosion resistance compared to standard zinc plating.

Strong, reliable hold

A dual-angle thread design delivers high pull-out resistance and secure fixing across a wide range of timber densities, making C2 Strong-Fix suitable for structural and load-bearing applications.

All sizes up to and including 75mm are fully threaded, while 80mm and above are partially threaded with a 70mm thread length, helping balance driving speed with fixing strength in thicker timbers.

Where C2 Strong-Fix Fits in the Range

C2 Strong-Fix sits above general-purpose woodscrews as a high-quality structural option for professional timber construction. They offer improved strength, speed and consistency without moving into specialist or ultra-performance fixings.

For everyday fixing, a standard woodscrew may be sufficient. Where additional strength, control and efficiency are required, C2 Strong-Fix provides a dependable upgrade.
