In Reply to: Lock Washers????? posted by Jiles on July 30, 2014 at 08:35:48:
In my mind, this is a very good discussion, thank you for posting this Jiles.
I attended a training session put on by loc-tite a couple of times, once as a technician for a John Deere Dealer, and once as a technician for a Cat Dealer. During this training they mentioned that they did a study of fasteners and how many cyclic loads the fastener could handle before they came loose. They used several different combinations of fasters/washers/lock-washers. Now I do not remember all the details from this, but what I do remember is that through course of the study, they found that the fasteners held in place with a lock-washer came loose sooner than the fastener held in place with just the flat washer. The fastener that was held in place with loc-tite did not come loose during the study or if it did come loose, it took a significant amount of cyclic loads for it to come loose.
After learning this, I now throw all lock washers away and use flat washers in its place, or loc-tite if in doubt.
