We use it frequently as internal thread of the machine. I would be happy if you can handle 500 or 1000 pieces with more quantity. Thank you for your consideration.
Most of the bike is a genuine float room. It is a must-have item of the maintainer. Because genuine is not stainless steel, I screw up the driver mountain, so I always exchange it. I bought it with a set with the same truss M4 stainless washer.
