That's impressive... they are pretty big bolts and only get torqued down to something like 45 lb-ft. I would get out the welder and weld a nut on the end, then back them out

Left hand rotation drill bit. They work most of time unless threads are galled.

***** punch and hammer first, see if you can dig in and knock it around CCW

What'd ya do? Run it down with the 1/2" impact ???
Too many ugga duggas.

Proceedure is 1/4 drive impact, 2 ugga dugga with gasket and a lil' rtv

These will come right out they are the cover bolts and overtightened. Hold a flat washer up where the bolt head should be tack it then weld it to the broken piece then weld a nut to the washer and take it out with a wrench.No welder cut a slit with a dremil or die grinder take it out with a screwdriver.Try driving it counterclockwise with a punch a an a hammer.The left handed drill bit I use sometimes, but most people don't have a left handed drill bit. Drill a pilot hole, drill it bigger, drill it bigger NoW collapse the hollow bolt with a punch. You're going to have lots if people say use an EZ out. That is always my last resort seen way to many of them broken off in the bolt which just complicates things.

Well I had the torque wrench on them set at 20lb. And wham........ to much I guess but I thought I followed what the manual said.

Thanks for the help y’all. I’ll give it a try and let ya know

All these replies are right on, very valid fixes, including the bit about a broken EZ out being trouble.
Start with the easiest and move up.
Years ago I bought 1/8, 3/16, 1/4 and 5/16 left hand drill bits, one each. I have carefully kept them for about 30 years, using when there is an UH-OH. Invaluable, worth many times their cost in aggravation. The vibration and constant CCW force does the trick. Most often the bolt will back out during drilling, certainly when the tip hangs on break-through. Don't break a bit though!!

Might be time to get the torque wrench checked. They do go out of calibration.

@Turbo4whl,

Where would you take that air tool to get it calibrated?

When I worked for the airlines as a aircraft mechanic we had a very sophisticated tool to calibrate torque wrenches. We had a two inch drive torque wrench, a breaker bar, ratcheting type pre-set torque wrench with a six or seven foot long bar we used on huge propeller center nuts, that held these big props, 12 ft. diam. onto the engine front shaft. It broke over at 1200 ft. lbs. We had to send that one out to Dallas, TX to be calibrated.

Torque wrenches that I've used are NOT air tools??

William, the Snap-On tool man will take and send out torque wrenches for calibration. Cost is about $80, but they will only do Snap-On wrenches.

I work on a Utility fleet. They have their own testing and labs division. We send torque wrenches there too.

As far as @Vbb199 system of ugga dugga's, I am familiar with this air tool system. This is a learned skill that may take years to master.

We send air tools out to a local repair shop that will reinstall any ugga duggas that are missing.

When you have your own air gun, that only you use , you can be sure of the ugga-duggas over a period of time!!!

Perry, at work we have a Snap-On quick check torque meter hanging on a building beam. It checks 3/8 and 1/2 inch wrenches. Set it for click type, digital or beam type.

When I see it, I am temped to set it to beam, and test my 1/2 air gun ugga dugga out put. I would need to do when there is no witnesses.

@Turbo4whl ,I won't tell!!!!!!
