Descriptions

• Nord-Lock steel construction (SC) washers are specially designed for use in structural steel parts.

• Designed to fit both HV and HR bolts and nuts.

• Designed to directly replace standard plain chamfered washers according to EN 14399-6 in order to add safety to high-strength structural preloaded assemblies encountered in steel construction, when exposed to dynamic loads or vibration. 

• In order to ensure an optimal contact surface between the bolt and the washer, each SC-washer pair has chamfers on the inner diameter. 

• Since the chamfer is present on both sides of each pair, it eliminates the risk of incorrect installation of the washer.
