Normally, I screw with Facom tool - only tool that I use less often, I take sometimes to more favorable Proxxon tools because usually already offer decent quality for the price. For example, but my 3/8 '' ratchet set of Proxxon who often used 1/2 '' and 1/4 '' ratchet boxes is Facom. The other day I so needed a 36er nut for the steering head of an old motorcycle and took me this Proxxon nut: I was already surprised when preparing the mother how much game has. This 36er nut has a clear width of 36.5! I do not know how much that game in such a large nuts is normal, but this nut, the nut that open visibly damaged, so I had to replace. I do not think that 5 / 10mm game are correct - for me the dimensional accuracy is next. Two stars still because my surface and the laser-etched size at the Proxxon tools always good like.
