1. Split washers have been experimentally proven to be ineffective locking devices and can even aid self loosening over time. And yet I see these things in use everywhere, so what gives? Quora digest
The split lock washers also don't make a reliable ground connection.
I always use internal tooth star lock washers.
Is this measured?
I agree that if the surface is not clean and there is some paint, oxidation, rust or anything else, this is the case. But if everything is clean, the contact area of the split lock is quite bigger.
I completely agree with GaryS, that they are good, as far as you use them in the proper conditions.
