How to Install External Tooth Lock Washers for Maximum Grip

Getting the installation right makes all the difference. Start by ensuring the washer’s teeth face the mounting surface — this direction provides the best bite. Clean the surface thoroughly, remove rust or oil, and align the bolt perfectly. Tighten gradually with a torque wrench, following recommended torque levels to avoid crushing the teeth. After tightening, check that the washer sits evenly and that the teeth are embedded in both surfaces. Replace washers after disassembly — never reuse them. Following these simple steps ensures your External Tooth Lock Washers deliver lasting, vibration-proof performance for critical applications.
