Lock Washers  Manufacturers, Traders, Suppliers

A lock washer is a type of washer that is used to prevent fasteners such as bolts and nuts from loosening due to vibrations or movement. Lock washers are typically made of metal and have a special design, such as a spring or toothed shape, that increases friction and helps to secure the connection.
The primary purpose of a lock washer is to maintain a tight connection and enhance the reliability of mechanical assemblies or structures.

Lock washers are commonly used in applications where vibrations are present or where secure fastening is critical.

Components used for secure and stable mechanical assembly in various structures and machinery.

Steel alloy pins provide strength and alignment, while mechanical washers distribute loads to prevent damage and loosening in assemblies.

Used together in automotive, aerospace, construction, and industrial machinery to ensure durability and stability in connections.

Nord-Lock created the original wedge-locking technology that secures bolted joints, even when exposed to severe vibration and dynamic loads. It is impossible for our products to loosen unintentionally due to the wedge created underneath the bolt head and nut.

Wedge-Locking Technology

Nord-Lock wedge-locking technology secures bolted joints with tension instead of friction. The system is composed of a pair of lock washers with cams on one side and radial teeth on the other.
Nord-Lock wedge-locking products secure the fastener in a joint which cannot be loosened even when subjected to extreme vibration or dynamic loads. The Nord-Lock range includes steel construction washers, wheel nuts, combi bolt washers and custom solutions.
