Structure Performance
1. Unique appearance
This type of product is round without point of force, averting the weakness that other angularity anti-theft nuts which with this point are destroyed easily.
2. The anti-theft structure of surrounded by all buried type in. The anti-theft theory of the products which are rational and scientific designed can be direct used inside the thing combining with bolt tightly that they cannot be direct destroyed by external force so can anti theft effectively.
