Lanfranco Railway Lock Nut Anti-Vibration Fastener For Rail Transit Equipment

Lanfranco Railway Special Lock Nut Stable Fastener For Vibration Condition

Originated from France, Lanfranco produces professional locking parts for rail transit. The special double slot structure provides outstanding anti-loosening performance, keeping firm connection under continuous vibration of train operation.

Locking Structure Principle

Symmetrical slots bring slight elastic contraction while tightening, tightly engaging with threads. The structure buffers impact stress and prevents reverse rotation loosening under vibration.
