Product information

Product benefits

Timber is not torn out-
The cutting point in the thread chamfer destresses the timber, therby preventing cracks.
No predrilling
Predrilling in not needed in most cases. We do however always recommend testing the application.
No discolouring
The anti-corrosion specialgrade steel prevents the timber and screw heads from discolouring.
Wobble-free drive
The TX internal, multi-tooth drive allows easy and secure screw driving from setting to countersinking.
Great look
The four milled ribs under the head ensure that the SK-Drill is easily and cleanly countersunk.

Applications

Ideal for bolting timbers of Terrace on wooden structures, mainly in the Scandinavian region.
