Heavy load timber joints with Spax
- Superior washer head clamping: The wide flange head pulls wood members tightly together, delivering high pulling force without requiring separate washers.
- Secure drive with T40: The T-STAR plus recess ensures optimal bit engagement and slip-free torque transfer during fast power driving.
- Corrosion resistance with WIROX: Full-thread steel construction coated in protective WIROX provides high load-bearing capacity and long-term durability in wood structures.
With the Spax construction screw, you create heavy-duty timber joints with exceptional clamping force. The wide washer head distributes pressure evenly across the wood surface and firmly pulls structural elements together without requiring separate washers. Thanks to the full thread across its 50 mm length and 8 mm diameter, you benefit from high pull-out resistance and dependable strength in timber framing, battens, and load-bearing woodwork. The t-star plus T40 recess ensures positive bit engagement without slipping, giving you smooth and controlled driving every time. Additionally, the durable Wirox coating shields the steel against corrosion, making it ideal for indoor use and sheltered outdoor projects.

SPAX wood construction screws - reliable, fast, economical
Where maximum reliability and easy processing are important, SPAX wood construction screws are the first choice. Their greatly reduced screw-in torque and very low splitting action ensure fast and effortless screw-in - a decisive advantage, especially in timber construction, where large structural parts are common and every time saving counts.
In structural timber construction, our partially and fully threaded screws are used for highly loadable, durable timber joints. The big advantage: complicated metal parts and fittings are unnecessary. This not only saves costs and assembly time, but also preserves the natural, aesthetic appearance of the wood. This creates stable joints with a pure wood appearance - without visible metal connecting pieces.
For applications such as stairs, timber elements or lathing in roof and wall, our universal screws with poppet head and partial thread offer maximum tensile strength. The large SPAX saucer head powerfully pulls parts together, while the optimised partial thread ensures perfect force transmission. Thanks to the shank length adapted to common wood thicknesses and the smaller screw diameter (e.g. 5 mm instead of 6 mm), you benefit from a higher penetration speed and lower material consumption.
Result: With SPAX wood construction screws, you achieve durable, strong and aesthetic wood connections - efficiently, economically and with noticeable advantages in weight, time and cost.
