The arbor screw holding the saw blade on my
compound miter saw has left handed threads and the bolt holding the blade on my
radial arm saw has left handed threads. Also your propane tank for
your gas grill has a left handed thread. I can understand why the saws have them
but why propane tanks? (My '61 Willy's Jeep also has
lefthanded lugs on drivers side) John Z

Wayne & Jim,
I used to run a manufacturing
plant where we provided parts to G.E. (Jet Engine Division), Pratt &
Whitney, (Jet and Piston Engines), Rolls Royce Engines, Hawker Siddeley, Bell
Helicopter, Sikorsky, North American Aviation, Thiokol, United Aircraft Ltd,
and most all Gear/transmission manufacturers.
I can tell you
unequivocally, left hand threads are very common, and in VERY high quality
applications. The examples I have given here are the highest quality of
mechanical components known to man ... NO exaggeration!

So the guy has not seen application where left hand
threads were required! He should to talk to G.E. or Prat & Whitney or
Westinghouse.-Rolls Roice ect. When you are assembling turbines whit
rotating masses that way over 800 lbs you torque the nuts up to 3000 lbs
foot and stretch them 100 degres.And yes some are left hand.The torque and
stretch are called out in the book and you better pay attenshion.Feel free
to forward to list.Jim McMullan 300F
