Precision leveling for timber substructures

Practical benefits

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.

In a nutshell

The right choise for

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.

Answered by specialists

What is this SPAX adjusting screw used for?: It is designed for precise, stepless leveling and aligning of timber battens and substructures without needing wedges or packers.
How does the adjustment mechanism work?: Drive the screw in fully, then reverse it counterclockwise; the retaining ribs under the head grip the wood to lift it to the desired gap.
Which driver bit do you need for this screw?: You need a T-STAR plus or Torx bit in size T30 for installation.
Is pre-drilling required in wood?: Thanks to the 4CUT point, pre-drilling is generally not required in softwoods, though it is recommended for hardwoods.
Is the WIROX coating suitable for outdoor use?: The WIROX coating provides high corrosion protection for indoor use and sheltered outdoor areas not directly exposed to rain.
