My suggestion is to make the nut out of brass and make it the same length as your delrin slider block. The longer the nut the more the pressure is spread out along the threads.
My winter project is to make a new longer nut and I'll post some pictures on my thread.

I do agree the furniture nut is not the perfect thing to use but you did not do yours any favor by using anti seize depending on the type you were using. The silver and copper colored anti seize contain metal and are not meant to be used as a lubricant. You can get a graphite based anti seize but it can still be abrasive.

I have thought about just treading the delrin block and see how that would work.
