Reliable timber fastening with Spax

Practical benefits

Accurate drive without splitting: You start driving precisely with the CUT point that significantly minimizes timber splitting during insertion.
High resistance to corrosion: You can safely assemble outdoor structures thanks to the durable A2 stainless steel construction.
Clean and flush countersinking: You achieve a neat aesthetic finish because the raised countersunk head seats smoothly into timber.

In a nutshell

The right choise for

With Spax 4.5 x 45 mm raised countersunk screws, you achieve solid, clean wood joints for your outdoor timber constructions. The cut point ensures accurate placement and minimises splitting, making pre-drilling largely unnecessary in softwood. Thanks to the partial thread, timber components are pulled tightly together without gaps, while the raised countersunk head with milling ribs seats smoothly and flush into the wood. The t-star plus T20 drive provides maximum torque transmission and prevents bit slippage during driving. Made of durable A2 stainless steel, these screws reliably resist weather and corrosion, making them ideal for exterior cladding, fencing, or damp spaces. This pack contains 200 screws.
