Tool kits with hex wrenches

Hex wrenches

— keys with a working profile in the form of a hexagonal protrusion inserted during operation into the corresponding recess on the head of the fastener. In contrast to inbus keys similar in design (see the relevant paragraph), in this case the mentioned protrusion has an even shape, without specific elements. This makes it somewhat difficult to use such keys in some hard-to-reach places, but in most cases it is not a disadvantage, and the simplicity of the design has a positive effect on the cost.
