Tapping into PEEK

Tapping into PEEK

Tapping into PEEK

(OP)
Anybody have any info on whether unfilled PEEK can be tapped into, or if it needs helicoils? My gut tells me that helicoils are necessary, but I just don't have any info to back it up. It'd be an M5 tapped hole, and I'd be putting about 40lbs on the thread, in tension.

Thanks.

RE: Tapping into PEEK

Not sure about PEEK but we routinely tap pomalux & I think delrin.

I was nervous the first time I tapped pomalux but it seems to hold #4-40's OK.

KENAT, probably the least qualified checker you'll ever meet...

RE: Tapping into PEEK

Peek has a lot higher tensile than POM.  But, if you are looking at a situation where you would normally put a helicoil in (say) soft aluminum, then put coils in the PEEK.

RE: Tapping into PEEK

Hi.

Depending on PEEK (and there are choices), tensile strength as high as 15,000 psi is reported at ambient temperature (ISO 527-2/18/50).

What I really like about this material is the retention of mechanical properties, even when its glass transition temperature is exceeded.

Here, if you think this helps:

Good luck!

RE: Tapping into PEEK

I can't tell you if it will meet your specs but the medical industry has been tapping PEEK for years.
