Default What size wire to use for 4-40 threading die
mecam, threaded couplers are OK, I suppose. They are usually made of brass, and I have found out that they are weak where the coupler body and the threads meet. Check them out and draw your on conclusions. The threaded ends I described earlier are made of steel, and when properly "silver" solder, inside the homemade brass coupler produce a stronger coupling than a brass 4-40 threded end.
