Allen keys T

The T-shaped Allen keys from the Beta Utensili brand are particularly useful because the joint at the bottom of the key allows you to conveniently position the hexagonal male at an angle of up to 50 degrees.

It also allows you to limit the tightening effort when using it at a 90-degree angle in a fixed position.

Another great advantage is the hexagonal shaft that can be stopped in the desired position along its entire length and the safety lock prevents it from being extracted inadvertently during use.
