Really like the Nordic lock washers
I love nord-lock washers, they are great at keeping bolts in on my race car despite the vibrations you get from the race track.
Needed this for attaching brake calipers. Had removed the bolts a couple of times, did not want to take a chance on failure. Arrived promptly and work.
Person was great in assisting with ordering and shipping and the product works perfectly.
