Nord-Lock Group Om Nord-Lock Produkter Combi Nuts
Nord-Lock skapte den originale låseskiveteknologien som sikrer skrueforbindelser selv når de utsettes for kraftige vibrasjoner og dynamisk belastning. Det er umulig for våre produkter å løsne utilsiktet på grunn av kileeffekten under skruehodet og mutteren.

COMBI NUTS

Expect simpler assembly, fewer errors, and optimized efficiency with our combi nuts, combining a nut with a pair of captivated Nord-Lock original washers.

Combi nuts are ideal when a lack of accessibility in combination with loose parts make assembling and maintenance difficult. The advantages of the combi nut will streamline production for any manufacturer using serial assembly.

How it works

Each combi nut combines a nut with a pair of captivated Nord-Lock Original washers, with cam faces on one side and serrations on the other, giving rise to the wedge effect.

With movement only occurring across the cam faces, any rotation of the combi nut is blocked by the wedge effect of the cams.

Advantages

  • Faster assembly
  • Reduced risk of incorrect assembly
  • Lower risk of parts coming loose
  • Easier disassembly and reassembly during maintenance
  • Less time required to maintain production
  • Cost savings through improved productivity

 


Testing & Certification

The Nord-Lock combi nuts are tested according to DIN 25201.
