PE threads well x itself without an insert.
Nevertheless, if you need a machine thread in it, use a Tee-nut.
Propellor necked tee nuts jam well in the stuff.

 

I've used both brass and steel threaded inserts in it with good results.

 

yes.. it works well ..
over size the hole a 32nd to avoid spauling...

 

Thanks everyone for the responses, will try to do it tomorrow

 

Hi Dan:

I agree with Quillman - I prefer to drill & tap UHMW. I also use nylon screws to keep everything non-metallic.

 

I'll have to try that next time.

 

Threaded inserts work just fine with UHMW. I have used it drilled and tapped it as others have mentioned.

 

I drill and tap it too. I think I would skip the inserts.

Inserts are stronger and deal well w/ repetitive screw in/out and have higher torque limits..
