Nord-Lock SC, Construction Washers, M36 (NL36SC), Steel Delta Protekt® (Single Pair)
Nord-Lock washers secure bolted joints with tension instead of friction.
Based on the leading Nord-Lock wedge-locking technology, the Nord-Lock steel construction washers (SC) are specially designed for steel construction applications and to fit HV sets and HR sets (bolts and nuts in accordance to the European standard EN 14399-4 and EN 14399-3).
Nord-Lock SC-washers are designed to directly replace standard plain chamfered washers according to EN 14399-6. The torque requirements have to be adjusted accordingly to our torque guidelines for HV bolts. Nord-Lock SC-washers are CE-marked for use with HV bolts and the safe usage with high-strength bolts has been confirmed by the General Building Supervisory Approval No. Z-14.4-629 and by the European Technical Approval 13/0246 issued by DIBT.
