Having double wings, JIS B 1185 butterfly fly nut can be manually tightened or loosened during use without carrying tools, so it has a wide range of applications. Due to the complex shape of the fly nut, the current production of the butterfly nut requires multiple processes such as cold heading, punching, punching, and tapping before it can be formed.
