With our Carpenters Mate 200mm wood screw, you will be able to complete structural projects quicker with greater efficiency and safety. Browse our range of 150mm to 200mm wood screws below.

Our Carpenters Mate screws are manufactured from carbon steel and stainless steel and can be used for a range of applications including fixing sheet materials to roof insulation, landscaping projects and loft conversions. You can use both our Hex Heads and Flat Heads for all these projects. Our fasteners have been designed to revolutionise the way in which carpenters’ complete projects by replacing the traditional M10 coach bolt. As you know, this method is time-consuming and requires several tools and components. A Carpenters Mate Pro Hex Head screw simply requires a cordless drill and a drive tool. You can save money on equipment and time as each screw takes seconds to secure, faster than an M10 coach bolt – if you don’t believe us, see for yourself!
