Star Washer

Star Washers are multi-tooth elastic locking gaskets customized for metro, high-speed railway signal & insulated fastener assemblies.

Its radial star teeth bite tightly into metal contact surfaces to realize dual anti-loosening & conductive grounding performance, stops bolt loose-off from high-frequency train vibration, avoids signal circuit open/short faults caused by poor contact, reduces frequent signal equipment disassembly & maintenance downtime for urban transit and high-speed ballastless track lines.
