INVISIBLE HEAD
Aesthetically pleasing and longlasting
fastening, thanks to the
extremely small conical head that
becomes ever less visible in the
wood as time goes on
TIGHTENING FORCE
The inverse underhead thread
generates excellent grip capacity
for the screw, which allows for
perfect closure of the joint as well
as stable fastening. The doublenotched
tip increases this effect.
AGGRESSIVE ENVIRONMENTS
A4 stainless steel screws guarantee
excellent resistance to
corrosion even in very aggressive
environments. The A4 version
with a coloured head is ideal for
invisible fastening.
