DIN6798 Finger Spring Lock Washer Marine Anti-Vibration Washer

TheFinger Spring Washer manufactured to DIN6798 standard in J-type (internal tooth) and I-type (external tooth) configurations delivers reliable mechanical locking under severe vibration. Unlike the typical Split Lock Washer that relies on a single split-ring spring force, the finger spring Lock Washer integrates multiple serrated teeth bent to precise angles, creating positive bite engagement between nut face and mating surface for superior anti-loosening performance across all conditions.

For ship engine rooms, these washers secure generator base plates, pump motor housings, compressor mounts, and electrical distribution panel assemblies. For renewable energy installations above deck, the Finger Spring Washer is also specified for Solar Panel Mounting systems exposed to wave-induced motion and wind gusts. In structural applications requiring high-torque rigidity on par with GB858 retaining ring standards, our DIN6798 tooth lock washer serves as a complementary solution where rotational locking is the primary requirement rather than pure axial retention.

SINOFASTENER produces DIN6798 finger spring washers with consistent tooth angle tolerance ±3°, ensuring uniform locking torque across every batch. For customers comparing Split Lock Washer alternatives with GB858 retaining ring solutions, we provide application engineering support to identify the optimal locking and retention fastener system for each unique operating environment.
