New Style of Lockwasher

Here is a link to a new style of lockwasher we are looking at at work. They are better than split washers and nylock nuts.

 

The salesperson has a vibration stand that shows how clamping force goes down with vibration using the other types of locking devices. These Nord-Lock washers actually increase clamping force when they loosen.

 

I have not used them on my bike as of yet but plan on it when Fastenal starts stocking them at work.

Yeah it was pretty cool, the salesforce has a pretty good demo where they have a vibration rig connected to a computer that measures clamping force. They bolt it up with the various locking devices and you can watch the nuts loosen.

 

At work we are looking at this for a cooling tower application where the bolts keep loosening. Actually I am looking at it. Management is afraid of anything new, no matter how well it may work. So I showed them this, if they don't use it I will not be tightening any bolts in the future.
