Inverse underhead thread (left-handed) for excellent grip.
Front triangular thread for excellent grip and wood penetration.
Small conical head to ensure it is hidden in the wood.
COLOURS AND MATERIALS
Available in carbon steel with special coating and in A4 stainless steel.
FIELDS OF USE
Exterior use; appropriate for service classes 1-2-3.
Aesthetically pleasing and longlasting fastening, thanks to the extremely small conical head that becomes ever less visible in the wood as time goes on.
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.
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.
