We've had a few Prieur style orange body cords lose the brass set scew over the years. I've decided to remedy this problem by applying heat shrink tubing around the entire body of the two prong connector. The other problem is the screw itself. The screws are made of bass and in more than one case has snapped apart when being tightened (often times by overzealous fencers who borrow my screwdrivers without asking). I am planning on ordering replacement screws. These will be of the headless hex set screw variety which will be stainless steel. Here comes the question part: 1. Any problems with using these type of screws besides the fact that most likely the tightening device will have to be an allen wrench rather than a screw driver. 2. Does anybody know what size I should be ordering? I'm away from any and all Prieur body cords for the next couple of weeks and in addition don't have a set of calipers handy. I'm thinking they are 3mm Diameter by .5 pitch and 5 mm long, but that is just a shot in the dark guess. Could anybody help with a definitive measurement? Thanks in advance.
