Harrell Tuner

[WOLFMAN2018]

Does anyone know what thread and pitch the machine screws are that hold the tuner on the barrel?
TIA.

The standard Harrell Rimfire Tuner is a clamp-on device. No threads.

The Harrell website shows "Tactical Tuner Brakes" with thread sizes.

There are 2 screws that clamp it to the barrel. From what I can tell, they are #5 but not sure of the pitch.

Find a ACE hardware, or store that has a good selection of screws, etc., and go visit them with the tuner. Big box stores may/may not have what you need, but the local stores may be better stocked.

Definitely not 8-32. It measures .1225 diameter, which is #5.

I bought a box of them, it was cheaper than buying just a couple...

Another totally incorrect answer from up north. No threads? Except for the screws that make the clamp, clamp!! Another perfect example of how misinformation spreads wildly on the web, especially when the poster has little to no experience.

I apologize, Scott. While the Harrell tuner remains a clamp-on device, I misunderstood the question and thought the OP was asking about screwing a tuner to the muzzle.

I salute you for single-handedly helping prevent the wild spread of misinformation on the web. No doubt should I make other posts there will be mistakes. You and LS are welcome to follow.

Thank you WOLFMAN, I'm writing that down. It is so helpful when the OP circles back and answers his own question for the rest of us.
