Macsim T17 batten and general-purpose screws are heavy-duty timber fasteners designed for secure, efficient fixing in structural and exterior applications. They are suitable for fixing hard and soft timbers to timber and thin metal up to 0.7 mm, making them ideal for projects such as decking sub-frames, pergolas, fencing, gates, furniture, landscaping, and general construction work.
 
 Engineered for strength and ease of installation, these screws feature a Type 17 fluted needle point that captures timber chips and enables fast penetration without the need for pre-drilling. The coarse saw-tooth thread improves driving speed and holding power, while shank knurling reduces friction and helps prevent timber splitting or lifting during installation. Nibs under the head assist with clean countersinking by clearing debris, and the bugle or self-embedding head ensures a flush, professional finish with minimal surface damage.
 
 Finished with durable galvanising for corrosion resistance, including Class 3 protection for outdoor and treated timber environments, Macsim screws deliver long-lasting performance in demanding conditions. Combined with a hex drive for secure engagement, they provide reliable, high-strength fastening with efficient installation and a clean finish across a wide range of timber applications.
