Heavy timber fastening with Spax screws
- High clamping force: Thanks to the wide washer head, you draw timber components tightly together without sinking the fastener deep into the wood.
- Split-free driving without pre-drilling: The 4CUT tip displaces wood fibres effortlessly, allowing you to drive screws cleanly without splitting near edges.
- Maximum torque transfer: The T-STAR plus T30 drive ensures a secure bit fit so you avoid slipping during heavy structural assembly.
With the Spax timber construction screw 6 x 220 mm, you create exceptionally strong joints in load-bearing timber frame and roof truss structures. Thanks to the wide washer head and partial thread, you pull thick wooden beams tightly together without sinking the head deep into the timber. The innovative 4CUT point prevents splitting and eliminates the need for pre-drilling in most timbers. Furthermore, the t-star plus T30 drive ensures maximum torque transfer without bit slippage, while the wirox coating delivers significantly higher corrosion protection for your heavy timber assemblies.

SPAX wood construction screws - reliable, fast, economical
Where maximum reliability and easy processing are important, SPAX wood 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.
