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.

Once the lock’n bolt S is tightened, it is impossible to loosen it without a special tool. This revolutionary bolt prevents recent theft problems of metal resources with construction machines, outside facilities, fence grating, banisters, etc.
When the bolt head is rotated clock-wise (in the tightening direction), the force is transmitted by screw head, and screw is tightened.
However, when bolt is rotated couter clock-wise (in the loosening direction), the force is not transmitted to the bolt, since the bolt is designed to rotate counter-clock-wise freely.
Length of the bolt can be reduced when necessary using washer, spring and small round screw.
The short length bolt can be applied to M8 size or bigger(bolt diameter of 8 mm or more).
