Unfortunately, the Torx Nuts are inside too flat chamfered so that they can be stuck not quite on the Torx screw heads. (Tested on screws on a Mercedes-Benz.)
Since the profile of the screw heads is slightly conical, then sit over the entire height incorrectly, and the risk of the screws Vernudelns is great.
But halfway matter: As a lover of a 3/8 "-Knarre and / or torque has an extensive cheap Torx set, and if you're careful, you can use it halfway.
When tightening to less accessible places the risk of the screw head Versauens is especially great because you nuts just can not quite put on, and then there still slightly tilted.
As cheap junk I'd 'me again buy (so you all there is), for the sizes commonly used but now I have beautiful Hazet nuts.
