Specification Sheet

Nord-Lock washers are 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
washers is continuously growing. 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.

Nord-Lock laser marks various sizes of our products with the Nord-
Lock brand name, control number and a type code. This is to ensure
that all of our customers receive genuine Nord-Lock washers and
enables full traceability down to the first assembly.
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 and products are laser marked, enabling full
traceability down to first assembly – even when using bin
systems for fastener supply.
