The Dead Drop 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, currency, and more. It has reverse threading on the bolt head for additional security, so if someone tries to unscrew it in the conventional manner, they'll only tighten it further.
The Dead Drop Bolt utilizes a 3/4" diameter bolt providing a large storage area. Its interior storage compartment has a diameter of .49" and a maximum depth of 2.81". Overall length is 3.43".
The Dead Drop Bolt is manufactured in the USA.
