Concave-convex nuts are nuts with a special structure. The design feature is that the upper nut has a concave part, and the lower nut has a convex part. The two are fastened through the concave-convex fitting principle.

[0003] The existing concave-convex nuts lack anti-skid and anti-loose capabilities, and are prone to loosening when subjected to vibration or impact, leading to connection failure. Moreover, the friction between the nut and the connecting component decreases, increasing the risk of nut loosening. This reduces the tightening effect and weakens the anti-loose performance of the concave-convex nut over time, requiring more frequent inspection and maintenance, increasing maintenance costs.
