They are a cool design they work okay and look nice the metal is softer than I'd like though (they are not Grade 8 like I wanted), and the Allen-Bradley hub drives seem to do the job. There will be a rounding of the center of the wrench socket The way out- The Allen wrench head spins when it is tight, in places where a standard socket cannot be used, and where a standard open-end wrench won't work either With a wrench end, you will achieve the same result- rounded corners on the bolt. Flat washers can also be adapted a bit to fit in certain.
