Precision leveling for timber substructures
- Stepless adjustment without wedges: You align wooden battens with millimeter precision simply by reversing the screw after initial insertion.
- Secure grip with T-STAR: The T30 drive offers superior power transfer so you work efficiently without bit slippage.
- Proven Spax 4CUT point: Thanks to the specialized tip geometry, you reduce wood splitting effectively even close to the edges.
With the Spax 6 x 80 mm adjusting screw, you can level and align timber battens and substructures against uneven walls or ceilings with millimetre precision. Simply drive the screw in fully and reverse it slightly; the retaining ribs beneath the flat head grip the wood to adjust the gap continuously without needing packing shims or levelling wedges. Thanks to the Spax 4CUT point, driving resistance is reduced and wood splitting is effectively prevented even near the edges. The t-star plus T30 drive ensures positive bit engagement for maximum power transfer without cam-out. Finished with a protective Wirox coating, this screw is built for interior finishing and sheltered outdoor applications.
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)
- Stepless 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 is a matter of millimetre-precise alignment of the battens. Whereas 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.
