Absolutely, in this place you do not want to lick you need tools from this hand. In the flare nut wrench, there is no size, it is a place where the hex socket on hand does not enter, so it is purchased without hesitation. I could purchase it cheaper than other net shops. Neighborhood home centers, car shops, and tool shops who had traveled over 5 houses were saved because there was no stock.
Because it is a 6-sided type, I bought it because it is hard to lick corners of bolts. It was good, but for the bolt I licked, the horn was too tight, and it did not fit. However, it is satisfying if it is a purpose.
