I know better, but just asking

Gents;

I must fasten some really well machined aluminum pieces, traditionally requiring lock washers. The AN bolts will be removed and re-installed frequently, so Loctite is out. Quite confined area, so safety wire will not work either.

Q: As I can place an AN960 washer on one surface, then a STOUT lock washer, followed an AN4-28 bolt. Can I possibly assume the ‘sprung’ pressure of the lock washer will exert enough force to secure the bolt in place.

As this is an an absolutely drop dead gorgeous upright, and would not be inclined to mar the machined surfaces. BUT, is this smart?

Have you looked at blue loctite? It can be taken apart easily unlike some other strengths. The downside is you have to clean and re-apply each time the bolt is removed which can be a pain in the neck.

Possible to use studs instead??

You won't like this answer, but there really is no way to know.

You haven't specified the materials, the size of the threads and bolt, the installation torque, nor the complete operating environment (static loads, cyclic loads, vibratory frequencies, thermal extremes, etc). Pedantic for emphasis.

A sprung washer just adds an indeterminate amount of "that is a little bit better than without it".

This may be the ticket.

Use these on my CV joint bolts and work well there.
