자주 묻는 질문
How do I keep bolts from loosening in steel structures?
Use Nord-Lock steel construction washers. They use Nord-Lock’s wedge-locking technology, which keeps the bolt in place even under heavy vibration, movement, or dynamic loads. The connection stays secure without retightening.
We use HV/HR bolted connections — how can we avoid preload loss and installation issues?
Nord-Lock steel construction washers prevent preload loss, reduce installation errors, and eliminate the need for maintenance. They provide reliable performance where double nuts, pal nuts, or retightening often fail.
Am I allowed to use Nord‑Lock steel construction washers in EN 1090 projects?
Yes. Nord-Lock steel construction washers are designed specifically for EN 1090 and EN 14399 HV/HR bolt assemblies and can be used confidently in preloaded structural joints.
How difficult is it to install Nord-Lock steel construction washers on site?
Very easy. They require no special tools, ensure consistent preload, and are easy to install even in challenging on‑site conditions.
When should I choose Nord-Lock steel construction washers instead of standard Nord-Lock washers?
Use Nord-Lock steel construction washers when working with HV/HR bolts in structural steel applications which are supposed to dynamic loads or movements.
Which washer size fits my HV/HR bolts?
Simply match the washer size to your HV/HR bolt size (M12–M36). The Nord-Lock Steel Construction Dimension Guide makes a selection straightforward. Consider a Nord-Lock washer underneath the bolt head and the nut.
Are Nord-Lock steel construction washers tested for extreme loads and vibration?
Yes. They are verified through Junker vibration tests and EN 14399 performance criteria, ensuring reliability under wind, dynamic forces, and temperature changes.
Are Nord-Lock steel construction washers CE-marked?
Yes. Nord-Lock steel construction washers are CE-marked as part of the EN 1090 certification framework. This means they are approved for use in loadbearing steel structures and meet the performance and safety requirements defined for construction products in the EU and UK markets, marked as part of the EN 1090 certification framework.
