The Spy Bolt is an updated and improved version of the old Soviet KGB “dead drop” hollow bolt used during the Cold War. It features an O-ring seal for weather-proof storage of small valuables, communications, etc. It has reverse threading on the bolt head for additional security. This new version utilizes a 3/4″ diameter bolt providing a larger storage area than the original. Its secret storage compartment has a diameter of .49″ and a maximum depth of 2.7″. Overall length is 3.43″
BONUS: The mega spy bolt now comes with 2 storage containers that fit neatly inside of the bolt. Use is optional, but these containers can come in handy if you’d like to keep more than one item separate within the bolt. The containers feature a water tight plastic screw top and durable glass transparent body. Capacity of each container is 4mL.
