JLC - Carstensen in line die set screw question

[Linko]

I have a 6BR Carstensen die and if someone also has one could you tell me if the seater stem set screw is just a metal screw that contacts the stem threads or is there a nylon inset or something soft that contacts the threads. I find it hard to think that the set screw just contacts the threads directly.

You can find the nylon tipped set screws at McMaster Carr http://www.mcmastercarr.com/

An appropriate piece of lead shot also works well in a pinch.....
