See recommended productsSpy Bolt® screw – spy compartment
29,12 $ VAT included
Spy Bolt® is a spy gadget which originates in the times of Cold War. Soviet agents used similar screw-compartments to pass confidential information and microfilms without arousing any suspicions.
Spy Bolt® compartment looks like an ordinary 3/4” steel screw. However, inside there is a small space which can be used for keeping precious items or secret information, hidden away from the third parties.
The diameter of the empty space is 12.4 mm and the depth is 71.3 mm. After placing a secret message inside, all you need to do is twist the mandrel of the screw together with its head (reverse thread), which is additionally tightened by a rubber o-ring. This way, the items placed inside the Spy Bolt® screw (e.g. a sheet of paper with confidential information, money or a memory card with data) will be protected against water and curious eyes of third parties.
