Button head profile sits flush for a smooth, safe walking surface and minimal snag risk.
-
No. 10 x 2-1/2" from a 224‑piece bucket provides ample quantity for mid- to large-scale decking projects without constant reloading.
-
Collated for speed compatible with modern automatic screw feeders, cutting installation time dramatically.

Indoor and outdoor versatility designed to perform across a range of deck applications and environments.
Ideal use cases
Perfect for installing deck boards where a clean, uninterrupted surface is the priority. The No. 10 size and 2-1/2" length cover typical board thicknesses while maintaining strong pull-out resistance. Use on new deck builds or retrofits where a concealed-looking fastener system is preferred, and you want to minimize surface fillers and sanding after installation.
Practical tips for best results
- Pair these screws with the corresponding Cortex plug system to achieve a truly hidden look once the plug is set and sanded.
- Use a compatible collated screw gun for rapid, consistent drives and to maintain uniform depth across the deck surface.
- Mark a consistent starting point and drive at a controlled speed to prevent overdriving or stock flex in softer woods.
- Pre-drill where necessary for particularly dense or brittle boards to protect against splitting, then drive with the Torx TTap bit for best results.
