The Nord-LockŪ system consists of a pair of washers with a wedge-locking action, which is a unique method that uses tension instead of friction. It is a high quality product with documented success in many industries worldwide, and is the washer utilized by a broad range of propeller manufacturers. Nord-Lock wedge lock washers have been rigorously tested and approved by independent institutes as well as certification authorities. Nord-Lock wedge lock washers are used in numerous industries such as aviation, energy, transportation, offshore, mining and quarrying, construction and bridge building, manufacturing and processing, ship building, forestry and agriculture, heavy vehicles, and military. Our washers are approved by several industry standards and specified by numerous international companies. Over the operational life cycle, Nord-Lock wedge lock washers give increased operational reliability and lower maintenance costs while significantly reducing the risks of production stops, accidents and warranty claims. All Nord-Lock washers manufactured are laser marked with the Nord-Lock brand name, control number and a type code for increased traceability and to facilitate authentication. Note: SP Washers feature an Enlarged O.D. for use on large / slotted holes, painted / sensitive surfaces, or soft materials. |

These puppies work!
Incredible grip strength.
Nice to find true locking washers great product
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.
Excellent product, works great.
