Accurate levelling for timber substructures
- Millimetre precise timber adjustment: This Spax adjusting screw lets you align battens and counter-battens continuously and accurately without needing packing wedges.
- Maximum bit grip security: The T-STAR plus T30 drive ensures superior bit engagement, effectively preventing cam-out and transferring torque efficiently.
- Fast driving without splitting: The engineered 4CUT point reduces splitting near edges without pre-drilling, while the Wirox coating delivers robust corrosion resistance.
With the Spax adjustment screw 6 x 70 mm, you align and level timber battens and substructures with millimetre precision without needing packing shims or wedges. Simply drive the screw flush, then reverse it slightly so the holding ribs beneath the flat head grip the wood and adjust the spacing accurately. Thanks to the engineered 4CUT point, you can drive smoothly into softwood without pre-drilling while preventing timber from splitting. The t-star plus T30 drive guarantees a secure bit engagement with optimal torque transfer, while the robust Wirox coating delivers reliable corrosion protection.
Product description
- Optimum countersinking of the screw head thanks to special flat head
- Fast and reliable processing with little effort (more screws on one battery charge)
- Infinite levelling of wooden substructures on solid wood substrates, wood-based materials and boards
- Effectively reduces the risk of wood splitting, even at small edge distances
- Without pre-drilling (depending on the type of wood)
With a wooden substructure consisting of battens and joists on wooden substrates, it comes down to millimetre-precise alignment of the battens. If you previously had to make do with washers or wedges, you can now save yourself the trouble with the SPAX adjusting screw.
By screwing the screw all the way in, the screw head is completely countersunk. When you then turn the screw slightly to the left, the holding ribs located under the screw head clamp into the wood and the batten is lifted off the substrate over the desired distance.
Our set screw also offers our own SPAX features, such as the T-STAR plus force gripping system, the 4CUT and the wave profile. The flat head allows optimal countersinking and offers high pull-through resistance. Our WIROX coating ensures that SPAX adjustment screws can be used both indoors and outdoors, as long as they are not exposed to the weather.
For you, this means: easy and millimetre-precise levelling of the support slats without wedges - this installation method is extremely time-saving.
