The HEICO-LOCK® HLK-Washers offer high quality anti-vibration security for HV sets according to DIN EN 14399-4 and DIN EN

14399-8.

Even under extremes of vibration or severe dynamic loads in steel construction the HEICO-LOCK® HLK-Washers, which are approved by the German Institute for Structural Engineering (DIBt), provide maximum reliability. Due to the increased under head radius of HV bolts, the HEICO-LOCK® HLK-Washers are chamfered on the internal diameter to ensure optimal surface contact while tightening.
