I have a number of HamStick antennas that I use with my Truck. Over time, I’ve lost every one of the little pesky Allen Wrenches that they come with, and couldn’t find the size listed anywhere on the web.
I suspect they were designed with a 5/64″ Allen Wrench in mind, but I’ve noticed that occasionally slips with some of my worn set screws. A 2mm Allen Wrench is slightly larger (2.000mm vs 1.984mm), and seems to fit more snugly.
T-Handle Allen Wrenches, either 5/64″ or 2 MM can be found for < $4 on Amazon
