deep to ensure secure matching with the screwdriver. A deep recess, of a perfect shape, enables he same insert to be used for thousands of screwing operations.
which is capable of applying a strong tightening pressure.
with a smooth and sharp profile to guarantee rapid screwing with minimum effort, reducing the risk of cracking the wood.
