Internal Teeth Lock Washer

Good quality Internal teeth lock washers go through strict tests. They check things like hardness, how well they resist salt spray corrosion, and how they hold up under repeated loads. Certifications such as ISO 9001 or RoHS make sure they meet safety and environmental rules. Trustworthy suppliers give you material test reports (MTRs) and let you track the batch they came from. Modern manufacturing methods, like precise stamping and laser checking, ensure the size is right and the teeth are uniform. This helps lower the chance of them failing in important systems.

Proper installation

To install Internal teeth lock washer correctly, line up the teeth with the bolt or nut head and the surface they’re attaching to. Tighten them with even pressure so the teeth dig in without stripping. Use a properly calibrated torque wrench, this keeps you from tightening too little or too much. You can use flat washers with them or not, but it’s a good idea if you’re working with soft materials to prevent scratches or dents. Don’t reuse these washers in important applications (like where safety matters) because they can get worn out and lose their springiness. Tighten according to the torque guidelines we provide to achieve a balanced tightness without over-stressing the material.

Main uses

Q: What are the primary applications of Internal teeth lock washer, and how do they prevent loosening?

A: Internal teeth lock washer is made for places with a lot of vibration, like in cars or machinery. The teeth on the inside dig into the bolt/nut and the surface they’re attached to, creating friction that fights against spinning. This stops them from loosening when there’s movement or heavy loads, keeping the connection secure over time. The toothed design works well on soft materials or surfaces that aren’t perfectly smooth.
