O rings for broadhead tuning?

[Bullfrog 1]

Iam looking for rubber o rings to be able to turn screw in broadheads to orient them vertical. I had some from years ago but they are so soft they just smash flat?  Thanks. Bill

Here in MI I have got them at Tractor Supply.  I like to  hot melt  my inserts so I can orient my broad head anywhere I want it.

Check the plumbing dept. of any good hardware store.

Hey Bill,i've got some of the ones that they sell from 3Rivers. I didn't like them as much as I thought I would,and don't use the ones I have left. Send me your address and I'll mail them out to you.

I got some at Ace hardware.  They have a 4mm inside diameter and a 8mm outside diameter.  Kinda pricey at 20 cents a piece.  They work well for getting broadheads just right on carbons though!
