transportation, offshore, mining and quarrying, construction
and bridge building, manufacturing and processing, ship
building, forestry and agriculture, heavy vehicles, and
military. The number of industries that use Nord-Lock
washers are continuously growing.

in regular use, therefore Nord-Lock washers are commonly
retrofitted during maintenance, repair and overhaul

Nord-Lock washers are rigorously tested in all steps of
production to verify that the quality requirements are met.
Each batch is assigned a control number which ensures
full traceability and confirms that the washer is a genuine
Nord-Lock article. The control number is printed on the
package as well as on every washer pair, enabling full
traceability down to first assembly – even when using bin
systems for fastener supply.
In 2011 we began to laser mark our products with the Nord-Lock
brand name, the control number and a type code for increased
traceability and to facilitate authentication.
