1. The power of the rivet gun used is too small. When pulling the nail gun, it cannot be broken at one time. Pulling it twice, three times or more will cause burrs at the breaking point.
2. The quality problems of open blind rivets.
3. Length of open blind rivets. If the riveting thickness is thin and the length of the rivet is too long, there will be burrs after riveting, and the nail rod will be exposed.
