Thread pitch: Howa barreled action w/ factory threaded bolt knob

[stilesg57]

Hi all,

Picked up a Howa BA and the factory bolt handle is threaded (lucky me). Knob is plastic and I'll definitely want to replace it, but I have no idea what the threads are. Anyone familiar with this? Anyone else gotten a factory threaded bolt handle and replaced the knob and know what fits? Any chance it's 5/16-24?

1. Take knob to hardware store?
2. Attempt to thread knob onto 5/16-18 bolt?
3. Failing that, try more sizes til you find the right one, or find out it's none of the ones there?

I mean, looks about right from here, but I don't have it in my hand...

Hahaha yeah that was my next plan if nobody here knew

Just a guess but it might be metric.

Good luck with that.

I replaced mine with a Badger.

I replaced mine with a Badger.

Ooooh good to know — thanks! I’ll look for other knobs with the same pitch as the Badger then, which I think is the standard 5/16-24. Much appreciated!

I’ve also replaced mine with a Badger.

5/16”x24 is what you’re looking for.

Thread files are pretty cheap and you can use them to easily determine any thread size. I bought a set years ago and I think I have used them as gauges to determine misc. thread sizes a lot more often than their designed purpose.

Wait, when did Howa start threading their bolt handles? I’m pretty sure all four of mine are not threaded.

Only some are threaded. Not all. The bolt on my first creed wasn’t threaded, the bolt on the second creed is. The bolt on the .223 action that I got 2 weeks ago isn’t threaded. ?‍

^^^ Similar spot here. My first two Howas were not threaded (though those are more hunting oriented). But this one, a 26” threaded heavy barrel 6.5CM barreled action, is. Picture and description didn’t indicate that. No idea.

6lbs 4oz without any bottom metal btw. Looking forward to building out a heavy long ranger ?
