How to Select the Perfect External Tooth Lock Washer for Your Project

Choosing the right external tooth lock washer involves several key considerations. Ensure the washer’s hole size matches your bolt or screw diameter for a snug fit. The external teeth design offers broad grip and is ideal when you need strong locking on harder surfaces.

Material selection should reflect environmental conditions—stainless steel for corrosive environments, brass for electrical grounding, and zinc-plated carbon steel for cost-effective general use. Thickness and outer diameter must support the load without deforming. Lastly, check for industry certifications like ISO or DIN to guarantee quality and reliability for your critical applications.
