The C/Sunk Pro SM Timber Screws are heavy duty fasteners designed for secure, long lasting fixing in structural timber applications. Engineered for strength and reliability, they provide a high performance alternative to traditional coach screws, offering faster installation and greater holding power without the need for pre-drilling in most cases.

Manufactured from hardened steel, the screws feature a corrosion resistant coating that ensures durability in both indoor and outdoor environments. Their deep, sharp cutting threads are designed to drive quickly and cleanly into timber, reducing splitting while delivering and firm, secure hold. The countersunk head sits flush with the surface for a neat, professional finish, making them suitable for visible installations where appearance matters as much as strength.
The screws are compatible with standard driver bits and are ideal for applications such as decking, landscaping, fencing and structural joiner. Available in a range of lengths and diameters, they provide flexibility for a wide variety of projects, from heavy framing to general carpentry work.
