I know the old Jiffys just have the pin and cotter key combo, I'd drill the hole in the pin slightly bigger and use a jesus clip..
For the strikemasters or any other auger that uses a threaded bolt, just drill it out as mentioned in an above post, and use a pin and jesus clip and be done with it for a couple bucks instead of adding a lot of weight and spending some bigger dollars for this quick disconnect thing....Esox
