What is a Schnorr washer?

What are safety washers?
Safety washers were designed to prevent the rod end from going over a twelve point or allen bolt head if the heim joint fails. There is a slight tapered profile that will allow the heim joint to rotate without hitting the edge of the safety washer.
Do lock washers actually do anything?
They are still used on many applications in the belief that they will will “lock” the nut/bolt to the joint and prevent loosening. The body of evidence, based upon both experience and experimental results, is that they do not prevent loosening and can be shown to actually speed up the rate of loosening in many cases.
How tight should lock washers be?
Place the lock washer under the threaded fastener and ensure that it has a snug fit. If using a lock washer with teeth, make sure they will engage with the appropriate surfaces. If they don’t, swap out the washer for the appropriate one. Turn the fastener with a ratchet or wrench until it tightens to a firm connection.

Spring washers are locking washers that are used when there is a need to prevent a fastener from loosening as a result of vibration. They are also often called split lock or split ring washers.
What kind of lock washers work best?
Helical spring lock washers are the most common form of lock washer and are best suited to applications with smaller loads. High-collar lock washers are a kind of split washer. Internal use lock washers have teeth made to bite into the nut/screw head and surface it contacts.
Should you use a flat washer with a lock nut?
Depending on what you’re doing, the flat washer/lock washer/nut order on your bolt will affect how well the nut and bolt work. Flat washers may be used on either the bolt side, the nut side or both sides of the fastener. Flat washers help to distribute the force of tightening the nut by increasing the surface area.
