Thank you for making this video. Very useful and much appreciated. The rear adjustment arms (lateral links) on cars, for aligning toe-in on the rear wheels have both right hand and left hand threads on opposite sides of the central sleeve.
Sir, thank you so much for this! I am currently fixing up my first car (pontiac g3 20100 and me and my dad are changing the rare brake drums. I dismantled them to clean rust and didn't know where the brake adjusters went until I saw this video. Seriously, thanks!
Thanks for this video ! I have a sailboat which has left handed threads on studs attached to turnbuckles on the wire rigging for the mast. All turnbuckles have a left and a right hand thread . I needed a replacement stud for a turnbuckle and had to determine if it was left or right handed, your video solved the problem , thanks again .
Very good info, I will remember that, we had a 1970 Dodge Polara that had left handed wheel nuts, not sure what side it was but it was the only car we had that had left handed lug nuts.
Another place you'll find left-hand threaded components that wasn't mentioned are tie rods. The tie rod on my golf cart has got me baffled but with the clues/hints/rule of machinery laws I think I've got it licked. Hey thanks for putting this up we all appreciate the RU-vid help support system for everything built on the planet.
They can also be found in pumps for wells also. Worked for a well supply company, mainly pulling pumps and motors from wells to fix and replace them. It blew my mind when I first heard "that's left hand thread, you have to turn it to the left to tighten it"
most all cintrifucal clutchs on A.T.V use Left hand threads on centrifugal or some call starter or primarily,but its the one with 3 or 4 shoes in a drum.the plate or manual clutch behind the centrifical has reagular threads because it turns in opposite direction.great video tho.keep up the good work !

They pop up in places like that haha I hate it too when you don't know and try to break it loose when your actually tightening it more haha appreciate that! Thanks for Watching!!!
Regarding old 5hp Briggs horizontal snow blower/tiller engines: Are the threads (that secure a drive pulley) in the center of the crankshaft left handed?
I was hoping there were some kind of marking on the head of a bolt. Ir not, there should be! A small "L" molded or stamped into the head would be a great help. The old Chryslers used to be that way. We snapped many lugs off of my uncle's car back in the day. Good thing was we only had to snap 1 before we realized what we had done. Bad thing was us kids learned a lot of words we shouldn't have known at that age! :)
Great tip man. But im still having trouble on how to break a union from standing at a different angle i actually don't know which is lefty loosey and righty tighty. It bUgs me alot. Do you have any advice?
+NoobPlaya Solz Thanks! I hear ya, that would be hard to see, its a finer thread too. If you can see some of the threads then you could take some clay or even a piece of bubble gum to make a imprint, but the imprint will be a mirror so it would be opposite if that makes sense. Just like looking at the threads inside a nut, its backwards. If you can't see the threads, then i'd try lefty loosey first and see what it does. Thanks for Watching!!!
The old car does have right-hand and left-hand studs on wheel housing. One side of the car has the left-hand thread and on the other side of the car have the right-hand thread. It had something to do with the wheel rotations.
Dear Sir, Thank you for the video, Could you let me explain me how to know Right hand thread or Left hand thread for the Hex Nut please? It is really hard to differentiate the hex nuts for me. Looking forward to your help.
Your welcome, the simplest way to say it is, if you look in the nut, its like looking at a mirror of the bolt's thread, so its exactly the opposite of looking at a bolt thread, if the threads goes up to the left in the nut its a right hand thread nut. Thanks for Watching!!!
Goyot Ukhaa another way is if the nut has a line cut in the middle of it, it's left hand thread. Not sure about all other nuts, but it's common on welding equipment you will see them.
My old Mercury outboard has a left hand thread on the flywheel nut, that had me confused turning it right to loosen it and the whole motor turns in that same direction prop and all I guess the torque keeps it tight
theeasybeats Heard that, thats really unusual, luckily it didn't break or strip out on you from trying to loosen it. That is weird though. I've done that before on weedeaters and stuff, kind of embarrassing after you realize what it is haha Thanks for Watching!
Some left-handed studs have a "L" stamped into the end of the stud. Some left-handed nuts on gas lines have a notch in the center going around the nut.
you talked on the propane thread and all but nothing on how all flamable compressed gases have left hand threads and normally have a notch on any left hex nut telling you its a lefty. so non flamamble gases have right hand threads with no notch on the hex just wondering because if someone would have told me this when i was 16 id still be alive today!
Car wheel Lug nuts today are right hand thread requiring a re-torque of the wheel at 100 miles left-hand thread lug-nuts existed at one time on most car wheels I believe and I right ?
Yes you are correct, it wasn't on all makes but there was some that used left hand threads. Someone mentioned it before, may still be in the comments on this video not sure though its been a while. Thanks for Watching!!!
Bicycle pedals, non-drive side I believe, are left threaded. Wrench goes the same way on both pedals relative to the bike -both sides turn to the front which I believe pulls them off. Edit: other left, wrench to rear pulls them off. Be real, be sober.
