Rounded Bolt Head fix

[Gabe L]

Hey all, i have a bolt head on a plow that i was trying to get off with an air impact gun and vise grips. it was going good then i guess the socket was slightly too big and it completely rounded off the head but the bolt is slightly loose but i cant get it to come any looser and i switched the vise grips to the rounded side but no luck. i was thinking to just use the angle grinder and cut the bolt off and go buy another one but i don't want to mess up the moldboard on the plow. Any advice on how to fix this situation would be appreciated, thanks!

If you don't have access to a cutting torch or plasma cutter, maybe a pipe wrench?

I have hammered on an impact metric socket and have had good luck removing bolts like that.

good to know thanks

Can't you cut it off from the back with an angle grinder/zip disc? You're not going tur hurt anything if you nick the back of that board extension a little.

But why was there a bolt head sticking out in the first place? It should have used a plow bolt so there was no head protruding.

my grandpa had to replace some of the bolts way back and it is a standard bold on the top back of the furrow it is a little extention that helps flip the furrow

It should be a plow bolt so it will probably get loose in the hole when you chop at it with a cold chisel. If it is loose you can get a better grip on it, or if you're lucky it will be a grade 2 bolt and chop right off.

I agree, cut off the threaded end and nut with a sawsall.

Yup, they're typically called 'moldboard extensions'. Every plow around here has them, because the wire grass that grows so profusely prevents the furrow from turning easily; it just flops back down without those extensions.

Angle grinder with a zip disc should cut it off from the back in 5 seconds.

find a nut just bigger than head of rounded bolt ,place it over the rounded head portion of bolt and then weld center of new nut to old rounded head bolt let cool natural then remove with socket wrench

EXACTLY, NO "high tech" needed, snap the head off with a hammer and "cold chisel".

They make an extractor for rounded heads but usually I find an old next smaller size 12 point socket and hammer it on .

This should be a learning experience for those who refuse to believe physics, added to the extensive and growing list of things made worse by using an improper tool.

Toss the vise-grips into the corner where the torch and welder are stashed. That's what they are good for. The jaws are NOT sufficiently hardened to actually grip anything requiring significant torsional force. A person might as well use a C-clamp as an open-end wrench and not expect anything but a disaster.

I've had good luck with a sharp chisel and 3# hammer. They also make a nut splitter. Split the nut and knock it off. As some have said, I would do what ever on the back side.

probably what im going to do

Just cut it off with a grinder and be done with it.

ill probably use the air grinder to be more precise soi dont hit the moldboard

In situations like that with a rounded head on a bolt, it is good to have a set of Metrinch sockets like this. The sockets and wrenches work on the flats of a nut or bolt head instead of the points. You also don't need another set of sockets for metrics. The sockets work on SAE or Metric nuts or bolts.
