I have goldtip 5575 hunter camo arrows and realized that all broadheads won't screw into the threads. has anyone else experienced this and are there other inserts that i could use in these arrows?

What type of Bhead are you trying to screw in? I shoot 7595 advantage pro hunters and have not had any problems. Could it be a bad insert?

I've had the same problem before,seems to be a burr in the first thread of insert. Try this,insert point/bh so M/F threads are lightly touching then with light finger pressure push in while turning CCW (unscrew) until you feel a click(first threads start point/burr)Then reverse rotation to install,don't force it. If it does not go easily go back to CCW until you feel a second click,try to install at this point. After you get a feel for this it's easy and saves the arrow/insert. I hope it was just a bad batch of inserts that we got,I like GT shafts but their no good w/out tips. HTH
