Widely used &
globally approved
Nord-Lock washers are a high end products with
documented success in many industries. Our washers are
approved by several industry standards and specified by
numerous international companies.
Industries where Nord-Lock washers are used
Nord-Lock washers are used in industries such as: energy,
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

Often joints do not start to loosen until an application is
in regular use, therefore Nord-Lock washers are commonly
retrofitted during maintenance, repair and overhaul
procedures.

Traceability
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.
