Once upon a time I was buying a new left handed 1 1/4 nut for a bush hog and decided I should buy a new lock washer as well . A local experienced ( I think ) hardware gave me a blank stare like you dont see often. My question is - to be properly left handed and not a rebent POS it would have to be heat treated and probably assigned a part number . Can anybody give me such an example ? olcowhand probably can or others - anybody ? This website has people with better guesses than most peoples' facts . Late night dislodgement from brain !!

You know, I've never had the need to buy a LH lock washer, so this is a good question! Any time I've worked on a LH threaded part, I just re-used the OE washer.

I'm not sure I have seen actual left hand lock washers,although they must make them.
It would be very easy though,to re-make a right hand one into a left hand one.All you would have to do is put them in a vise,and give them a slight twist the other way,with no heating required.If done properly,they would not be just a re-bent POS.

I have never thought of that as an issue at all! All the left handed stuff I have encountered at work is usually pipe fittings that don't use lock washers. Maynard has the solution for that dilemma. Now if I can only remember that!!

I know some lock washers are so hardened, that if you tried twisting them, they would snap in-two. Cheap lower grade ones would twist without any problem.

I have a bunch of 1/2 inch ones. I'll have to see if they can be converted. Probably grade 5.

You'd only have to twist them just a fraction in the opposite direction,I think they'd be alright.

The cut in the washer is usually at an angle / to dig into nut and metal you are fastening, by reversing the washer you wold lose the locking part and as you tightened the nut you would actually cut into the nut. You need to find some "star" type washers.

Coop, you beat me to it. As I read the post I was picturing a lock washer and had the same thought.

I assume J1 comes from Piper J1 . You certainly don't need your prop to fall off . I have hand prop - ed cherokees and didn't think to remember about this. Thanks J1. Sparky

Glad you found an answer, Sparky. Now I know where to find good left-handed hardware.
