How to deal with worn-out threads on binding post?

Jim,

You can use a die to rethread the post to a smaller diameter.

You can find dies and Nickel-Copper nuts at McMaster-Carr.

Couple of suggestions:

Put some flat washers on first to move the tightening area further back, if there's room. Perhaps the threads are in better condition.

Try a nylock nut.

A piece of small diameter solder through the nut before you thread it on the post may help to fill the gap. You can even try dental floss or something similar.

My philosophy is to always try the easiest fix first.

When I owned Edison Price binding posts, I had the same issue. Threads are not worn out, the split barrel has become compressed over time by the nut.

Don't laugh, but you can cut a very short piece of wooden dowel rod and press into the center (between the split halves) and return it to it's original shape. Leave the wood in full time, it helps dampen the posts as well as stopping further compression.

The only caution, select the right diameter dowel rod so you don't crack and break the Edison price binding posts. I've also had great results putting Caig Pro Gold on the dowel rod and connector. Everything stays clean, conductive and free from corrosion.

Let us know if successful for you.

AlbertPorter: That looks like exactly what has happened. In fact, there has been so much compression that the two halves now look like an oblong

Thank you so much for the advice! I will be careful in choosing the right diameter dowel, and will let you know how it works out.
