Our security bolts prevent theft for equipments and products placed outside of buildings, construction machines, banisters, auto tire wheels, auto license plates, etc.
Once the bolt is tightened, it can not be loosened or removed without a special tool.
If someone tries to loosen it, screw head rotates counter-clock-wise, but the main threaded bolt does not rotate at all, and bolt can’t be loosened.
