Hello, Need a couple of the mounting nuts for a pair of Kilovac HC-2. Tried M14x1.5mm nuts, but none work on the HC-2. The threads on the M14x1.5 nuts I could find were too coarse for the fine threads on the relay. The spec sheet identifies the threads as M14x1.5-6g. Not sure what the "-6g" means; something to do with "fine" thread? 73, Mike, K4GMH
