Default French locks

A friend of mine that works on vettes for a living, recommends I not use the french locks, but use lock washers. He feels you can not torque then as well as they should be. I don't plan to have the car judged ever. Looking for you thoughts.

Thanks Bill

I've used lockwashers on most cars (non-judged)for years with no problems.

Using lock washers will work just fine. I prefer to use the french locks but I only use the stainless steel set. The standard steel ones will twist up when you draw down the bolts while the Stainless set will not...

IMHO,

Back in the day, there must have been a good reason why the factory engineers thought they should be there. They could have just used lock washers.....which cost a heck of a lot less.

when you try and torgue down the nuts, the dang French locks, will twist up underneath the nuts, buggers them up ... and I am sure if messes with torgue down.
I agree use lock washers.

The aftermarket French locks will "wad up" when torqued. The factory pieces were hardened to prevent that from happening. I used the French locks because that was the way the car was built...but I had to put grease under the bolt heads to keep them from twisting around.

But I wonder why they didn't just drill the bolt head and wire them like aircraft do ?

This is why we use the Stainless Steel Locks in the shop, they don't twist up. 7t1 is right, the originals won't twist up.... the steel repro's look like a twisted train wreck when you use them.

Aircraft fasteners that require safety wiring are generally low or non-torque applications...small bolts and wing nuts come to mind. More of a vibration issue. Besides, airplanes can't just pull over to the side of the road when something falls off.

When you bend the tangs on the lock...that is really secure. Same thing on the large bolt holding the backing plate to the spindle.

Every time I think about a cigar I remember hearing the best were rolled on the thighs of Cuba's most beautiful women. Makes me want to start smoking again....just for a moment.
