The expansion is a response to growing market demand for the X-series, which now covers new sizes NLX20sp, NLX22 (7/8"), NLX22sp (7/8"sp), NLX24, NLX24sp, NLX27 and NLX27sp.
Utilizing a unique multifunctional design, the X-Series combines the proven wedge-locking technology of the original Nord-Lock® washers with compensation against settlement and reliably securing bolted connections in the toughest environments.
This special design allows the X-series to secure bolted joints against thermal cycling, relaxation of soft metals and composites, or slackening caused by assemblies with multiple clamped components – scenarios common in intensive industries such as mining, railways, logistics and the energy sector.
In 2025, Nord-Lock® X-series washers became the first washers of this kind to be granted the CE marking. This certification is verified by an independent third-party body and requires extensive technical testing to demonstrate consistent performance and reliability.
“The extended X-Series range marks a significant step in strengthening Nord-Lock’s offering for demanding applications across multiple industries,” says Graham Souter, Vice President, Head of Business Unit Nord-Lock.
“We recognise rising market demands and deliver the finest bolting solutions in response, backed with rigorous testing and certified approvals.”
