I’m visiting my daughter and her fiancé did not realize the blade screw was left handed. Vise grips aren’t working. He wrenched it in there pretty good. I was thinking about cutting off the head and then trying vice grips, but if I don’t have enough screw to get ahold of that might be a mistake. Any other tips from someone that might have been in this situation?

10-12" cobras, pipe wrench, channellock nut buster style pliers, visegrip 10lw locking wrench, spiral extractor
Did you try visegrips on the bolt and a hex key in the center pulling at the same time?

I’m assuming we’re talking about a lawnmower. If you can get to it, at least a normal drill bit will help extract it if all else fails.

If not a lawn mower, no clue.

These bolt extractors seem to be direction agnostic, so if you have to drill.

Could be a circular saw too.

Not sure what tool it is but I'm thinking to try a manual/hand impact driver. But only if the screw is in the center of the spindle & not on the side of the spindle.

You're a little light on the background info, but... I assume the hex has been damaged so a wrench doesn't fit?
can you get a nut welded on so you can get a wench on it?
if you can get a good sharp hit or use an impact on it that can help loosen stubborn threads .

Circ saw? Can you use a screwdriver to trap the blade between a gap in the teeth and the shoe, then use a vise grip on the screw? May have to take the guard partly off.

That would be my approach too.

Normally I would use the locking button but it sounds like there might be excessive force needed so that might be not the best idea here.

The screwdriver frees up a hand too, one for the hammer, one for the impact driver.

Sorry, yes it is a circular saw. Success today. I hit the bolt with my map gass torch. To my surprise it immediately released. Thanks for the advice.

Was going to ask for a picture, we could give better advice, but sounds like you got it. I'm guessing that bolt was afraid of plumbers, maybe something from its childhood. Best not to ask any questions.

Side note: I've noticed a few threads asking for help from first time posters this last week and I want to make a big compliment to the moderators here. Because there's a balance between first time users posting, and spam on discussion forums. I never see any spam here, yet random people who need help are able to registry accounts, start new posts immediately without restriction (or maybe it hits a moderator que and he approves it) and be able to get help the same day.

I've been on other discussion forums or even on various subreddits that have various restrictions like you can't start your own post for 30 days after you register an account to deter spammers. Or you have to comment on 50 other posts before you can start your own. Yet the mods here have been working overtime to keep spammers out but still keep the community open and inviting. Well done :cool:

Gotta be careful putting that much heat on spindle bearings. In this case, the blade and washers acted as a heat sink.

I'll bet the bearing loved that.
So where is everyone getting their MAPP gas these days? I've seen two references to it today alone.

MAPPro is all that is available retail here. I buy any real MAPP at garage / estate sales.
