File:Theft-proof bolt before breaking.JPG

From energypedia

Original file(1,024 × 768 pixels, file size: 190 KB, MIME type: image/jpeg)

The image shows a theft-proof bolt before its final fastening. Once a specified torque is applied to its upper part, the nut breaks and only the lower, round-shaped part is left, leaving almost no way to apply a tool to loosen the nut.

Photo taken in Ndimba, Senegal.
