right hand Vs. left hand thread

[youngie22]

Okay- just so I am on the right track. Right hand thread is the old leftie loosie rightie tightie/ and left hand thread is the opposite left to tighten right to loosen??????????????????????? is this correct!?!?!?! don't want to hurt nothin'

[fiskyknut]

Yep.

[Jim Almquist]

Your thinking sounds good to me. righty tighty-lefty loosey and just the opposite for left hand thread.

[Farley]

you are correct, what are you working on that has left hand threads? I work in a fab shop/machine shop and seldom come accross left hand threads.

Huh, Thats odd. I am a c.n.c machinist and I make parts with left handed threads quite often. probably about once a week.

[Jim Uran]

Do gas lines still use the bass akwards threads?

There are a lot of automotive applications that still use left hand threads also!

Buy we usually dont figure it out until we over tighten it so much, we cross the threads

I am also a CNC Machinist.

Left Hand threads are very common.

They are used on shafts that spin clockwise because they will tighten up as the shaft spins. Like on Blanchard Grinders.

Ford Festiva rear axle nuts?

Thanx guys; Was water pump/ fan assembly for me. THought I was right in my thinking, but was second guessed, had time to check here and I also started the motor to watch which way they spun. Feels REAL good to have truck home from deer camp finally. Made it home this morning @ 1:30. For a nap and dinner soon!

I know we have left hand threaded rod in stock, but just one bar and it rarley gets used. All the threads we turn are regular thread. Maybee a left hand thread here and there. Or maybe the parts that use l.h. thread are run on a different machine. But we just make parts for our own company projects, no outside work.

I see a lot of left hand thread on propane/gas fittings. On propane fittings the nut (where you place your wrench to tighten) will have notches in it to indicate it is left hand thread. I am not sure if this is only on propane fittings or if it is used in other applications.
