Overview
|
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. |

Actually used these on a Kitchenaid mixer which vibrated the head retention bolts out every time it was used for kneading bread dough. This washer set worked perfectly to stop the vibration from turning out the bolts!
