Key features

• Material: Steel — durable and strong for demanding applications.

• Size: 1-1/8 inch (nominal). Designed to fit standard bolts for compatible assemblies.
• Locking action: Heavy split design helps bite into the nut and surface to resist loosening under vibration.

Benefits

• Enhanced safety by maintaining preload and reducing fastener fatigue.
• Improved reliability in vibration-heavy environments.

To install, place the washer between the bolt head or nut and the mating surface, then tighten to the recommended torque. The split edges bite into the surfaces, creating a locking action that helps prevent loosening over time.
