Anyone who can lend 27mm 6 point socket

Haha, you guys are too smart. I was turning in the wrong direction and rounded the nut

Another easy way, is to set your ratchet for "off", then turn it in your hand. That's a help on upside down and hard to access bolts. That will tell you witch way to turn with your end wrench.

Thanks but I was able to fix it myself. Will keep you in mind next time

I started to post the Right Hand Rule. That's a good illustration. People commonly use an utter garbage mnemonic for tightening/loosening, when the RH rule is simple and clear.

Applies almost everywhere. Exceptions I can think of are left bicycle pedal, and right side bicycle bottom bracket shell which both have left hand threads. And turnbuckles and some similar adjustment things, which have bits threaded each way.

Also - 60's MOPAR lug nuts on one side (and I always used to forget which side)!!!

Early Husqvarna counter shaft sprocket nut was left hand thread. I managed to break one off trying to loosen it. Also some mirrors on street bikes have one left hand thread, and one right hand thread.

right hand mirror and bottom jam nut of shift lever adjuster on most jap bikes are left hand thread

Yamaha is the one I know. IIRC it's left hand threads on the right side (brake lever perch) so both mirrors loosen when bumped.

My 1st car was a mid-60s Dodge. I doubt I ever knew that, or ever removed a wheel. Could have gotten interesting...

My second car had knockoffs to attach the wheels, and the ones on the right side have LH threads, but they have arrows on them showing which way to knock them off.

As far as the bicycle pedal, they loosen fairly quickly on the wrong side. How do I know? I once installed a unicycle wheel backwards. Only figured it out after the pedals started working their way out. For a quick fix I pointed the seat in the other direction, until I had time to reorient the wheel.

Or in the case of several bikes that I bought new, so that the wind can loosen them. I can still remember riding my brand new 1997 Ducati Monster from Fresno back to Pleasanton and being unable to keep the lift mirror in place. I finally stopped at Carnegie when I was 80% home and borrowed a wrench from somebody there to tighten it up. The left mirror on my 790R came loose riding it home as well, but that was only about 15 miles, so not as big of deal.

I think the early 60's Pontiacs had reverse threads on the lug nuts on one side too.

According to this guy: https://www.youtube.com/watch?v=jXxulZvCt_M

Chrysler was the last holdout to have reverse threads on the left side lug nuts. They were gone by 1975. He explains how it was a holdover from horse drawn carriages with a single center nut holding the wheel on. Can't find anywhere noting when all of the other car manufacturers switched, but quite a few other brands had them in the 50's.

The weird thing is that with those central bolt systems on relatively modern cars, they were mostly threaded opposite the Chrysler lug bolts--no clue about carriages, but MG & Ferrari used LH threads on the right side for the central retaining bolt/knockoff. It may be a holdover, but the sides swapped somewhere.

Lotus apparently used LH threads on the left side knockoff, but their threads were cut differently, and they claimed it was correct. I'm not a mechanical engineer, but if the wheels didn't fall off, it works for me.

My 69 Alfa Romeo Spider had LH lugs on left side. I think they kept doing this well into the 70's.

you actually need four different configurations due to front & rear wheels having torque in opposite directions.

Most modern centerloc wheels have pins to prevent drive/braking torque from rotating wheel relative to hub anyway.

Yes!

I remember when I got some NOS Cragars for my early 60's MoPar. Took quite a while to find a company that had the correct nuts in LH. The issue was that the A-bodies used fairly small nuts too. Then for years - no problem. Then some dufus at a tire place used an impact wrench and bolloxed up all five studs on one LH wheel. The LH studs by that point were almost impossible to obtain.

So I had one wheel that was LH threads, and three wheels that were RH thread.

I learned to mark the wheels with masking tape before taking the car to tire places after that.
