Although I described it as very convenient in the previous review, one question and opinion Small hexagon is circulating as a bolt nut for a car In the first place, detailed threads of less than 12 M are not used so much for general industries 4 Mark 7 Mark etc. Although I know, I do not think there is no entry of strength classification material. I do not care whether SS or SW or other thing is totally unknown, even if material change is made at the production side convenience (cost down), even if the material change is made to the user We do not know This is a problem We should specify either strength classification or material either If you use it for a car rather than a machine part, there are also scariences as there are many places to move
There is no problem in use. I tried to make things suffering before ordering but I am going to go a little more, so I will buy a little longer next time.
