The anti seize that I've used on load surfaces is this stuff.

Got some as a sample at a trade show and it works on pretty well anything you can imagine, bearings or bolts.
Our trouble is the 10/32 all thread is too small to effectively hold it in the thread and it gets pushed out from the extreme pressure.
An engineering friend of mine did the math and figured that it take about 350 lb force to lift a box of dirt weighing just 25 lb because of the lift angle.
I've just got through reading up on threading Delrin, and Travis you may be on to something there.
The only thing they talked about was to use coarse threads so the you got a deeper thread cut in the Delrin for more surface area. I've got some long threaded taps and 1/4-20 rod so I'm going to give it a try.
I'll post pictures later.
