Laser marking for washer pairs

During 2011 Nord-Lock will introduce a laser marking on each washer pair. It will include the Nord-Lock brand, control number and a type code. This new feature has been added to improve traceability and control.

The marking does not last, so Nord-Lock encourages users to make a note of the control numbers.

With the type code marking you can verify the type of washer you have in your hand. The markings are divided into three areas where the type code consists of 2-4 digits confirming the coating for steel washers or the alloy for stainless steel washers.
