It was optimal for rust and dirt removal of the shaft of the clamp. However, I regret not having entered the nuts. If possible, M21 should be sold for various sizes. (Even if I inquired directly from the manufacturer, it was no answer.) I am dissatisfied that the price is too high. Is it about cost 3000 yen? It is a sticky! It is!
Bolts and nuts of the tight frame were rusted, I thought that they would exchange even with nuts, and I was looking for good items to drop rust of bolts to remove them, and I reached this product. It was very helpful to rust in a short time.
