Tamper-evident bolt
First Claim
1. A tamper-evident bolt comprising a bolt head having an outer periphery and further having a blind axial recess formed therein, first ratchet teeth are formed on the outer periphery of the head, whereby a driving socket having ratchet teeth corresponding to the first ratchet teeth may be placed over the outer periphery of the bolt head to seat the bolt, second ratchet teeth are formed within the periphery of the blind axial recess of the bolt head, whereby a driver having teeth corresponding to the second ratchet teeth may be received within the blind axial recess to loosen and remove the bolt, and a seal received within and covering the blind axial recess, such that the seal must be removed for access to the blind axial recess, thereby indicating tampering with the bolt.

Abstract
The invention herein disclosed involves a "tamper-evident bolt". More specifically, the bolt has ratchet or splined teeth on the outer periphery of the bolt head which will accept a socket for tightening the bolt. In the center of the head of the bolt is a sealed or capped blind axial recess. The recess is fitted to accept a driver to release the bolt. In a specific embodiment the blind axial recess has ratchet teeth. A seal or cap is received within the blind axial recess such that the seal or cap must be removed for access to the bolt releasing means, thereby indicating the possibility of unauthorized tampering with the bolt.
