Frank,

That's ridiculous! A flat washer, beneath a spring (lock)

washer? The added compression of the lock washer will

keep the bolt AND the two washers from rotating. The flat

washer only gives the lock washer a FLAT surface to grab

onto, it doesn't reduce the lock washer's effectiveness.

I don't think the tang has much effect on whether the

bolt will come loose or not. Once fully compressed, compression

is at work , not the tang biting into the flat washer or

the bolt head.

If it weren't for your friend's misfortune,

I'd think this was a joke!

Has this SVA engineer ever worked on a car before??? In the

engineer's opinion, what would have been the "PROPER" way

to secure the cover?? Spring washers with no flats?

In his defense(not really!), I have seen plenty of "factory

bolts" on engines, etc., without flat washers, where I

thought there should be one.

Perhaps there are supernatural forces involved here, that

we mere mortals are unaware of? [img]/ubbthreads/images/graemlins/tongue.gif[/img]
