Nord-Lock Group About Nord-Lock Nord-Lock Steel Construction Washers

NORD-LOCK® STEEL CONSTRUCTION WASHERS

Nord-Lock Steel Construction (SC) washers are wedge-locking washers specially designed for use on steel construction applications in accordance with the European standard EN 14399-3 /EN 14399-4 /EN 14399-8.

How it works

THE DETAILED VIEW

The system consists of a pair of washers that use Nord-Lock wedge-locking technology. Each washer has cam faces on one side and serrations on the other. They also have chamfers on the inner diameter which ensures optimal fit with HV bolts. Since the chamfer is present on both sides of each pair, it also eliminates the risk of incorrect installation.

APPLICATIONS

Nord-Lock SC-washers can easily replace a standard plain washer as well as chamfered washer to prevent the bolt from rotating loose. The SC-washers are suitable for a wide variety of applications across the construction and bridge-building industry.

They are safe to use with high-strength structural bolting assemblies for preloading and are confirmed for HV-assemblies by the European Technical Assessment ETA-20/0010 issued by the German Institute for Construction Technology (DIBt).

SC-washers, NLO, NLSS and 254 SMO® are safe to use in non-preloaded structural bolting assemblies according EN 15048 and confirmed by the ETA-19/0813 issued by the DIBt.
