What’s the trick to get a CZ 457 bolt knob off?

[jrhtx]

I used a heat gun on it and no luck. Wasn’t sure how much heat it can take. I did not disassemble the bolt.
Suggestions? Thanks.

Try a soldering iron for direct heat.

I just tightened the knob in a vice wth rubber on the jaws and used the bolt body for leverage

It's got loctite on it. Wrap it in rubber and spin it off with a set of channel locks or vice grips......you don't need heat.

Just wrap it with electrical tape and spin it off with vise-grips

Combination of leather, bolt body as leverage, and heat. It’s slathered in threadlocker under there.

Thanks, try it tomorrow.

I have a heat gun that you can set the temp on. I believe I had it at 640 and it spun off easily after that.

Mine is a low end Harbor Freight model. Just hot/cold.

Electrical tape worked for me.

That's all I did too. If you don't care about the old factory knob, you don't need the leather!

My spherical bolt knob is HEAVILY engraved with some super fancy vise jaw pattern.

Not THAT is a bolt with STYLE *and* GRIP!

Just spin it off with force and then put the L3I knob on

It came off with more heat.

Yea, I used a torch (with the flame pinpointed on the ball) when on the last 4 CZ 457 knob upgrades. Not enough heat to get anything glowing but enough where you know the locktite turned to powder. That said, when you use heat, it can make the leather wrap/rubber jawed tool a little tricky to do. Truth be told, I've ended up scratching more than a few of the knobs removed. I really don't care though. A replacement factory knob can be had for $10 and It's not that I would ever put one back on .
