The set provides a wide range of tools for tightening and loosening screws and bolts of various sizes. The heads and bits are made of high-quality vanadium steel. The magnetic bits make work easier and faster, even with the smallest screws. The two-component handles, with an ergonomic shape and non-slip surface, facilitate precise work and allow you to fully transfer the strength of your hand to the screw or bolt. The set is packed in a sturdy case with separate places for each tool.
