As other reviewers note, they are not of the highest quality. That's to be expected for the price, so I'm only deducting one star. If they were advertised as a Gr8 (they aren't) or by a more reputable brand it would be appropriate to deduct a few stars. The hex in the head in particular can be messy with hex wrenches. When used in places where fasteners must be repeatedly loosened and tightened (such as lathe holders), rounding of the hex may occur. Either way, they're good for non-critical, "set and forget" applications.
