Nord-Lock Group Over Nord-Lock Producten Originele Borgringen Materiaalkeuze

Nord-Lock ontwierp de originele wigborgtechnologie die boutverbindingen fixeert zelfs wanneer ze blootstaan aan extreme trilling en dynamische belastingen. Door de wig die onder boutkop en moer ontstaat, kunnen onze producten onmogelijk zomaar losdraaien.
