Reliable and durable

Purchased these for a custom bike build. The finish is smooth, there are no sharp burrs, and they hold the axle nuts securely. Great value for the price compared to local hardware stores.

Perfect fit for my machinery repair

These six-claw circlips are exactly what I needed to secure the round nuts on my lathe. The manganese steel feels incredibly sturdy, and they snapped into place without bending. No more loosening due to vibration.

Best anti-loosening solution

I have tried standard washers before, but these locking circlips are superior. The six claws grip the nut perfectly. Highly recommended for any high-vibration automotive application.

Solved my vibration issues

My pump assembly kept coming loose until I switched to these lock washers. The design is simple but extremely effective. Installation was straightforward, and they haven't moved an inch since.

Good assortment for the workshop

Having a mix of sizes in the kit is very convenient. The 65MN steel version is tough enough for heavy-duty use. One size was slightly out of spec, but the rest were perfect.

Great quality, slightly tight fit

The stainless steel option is excellent for outdoor equipment where rust is a concern. They were a bit tight to install initially, requiring a good pair of pliers, but once seated, they are rock solid.

5 FAQ

Q: What is the difference between 304 Stainless and 65MN Manganese Steel?

A: 304 Stainless Steel provides superior rust and corrosion resistance, while 65MN Manganese Steel offers higher tensile strength and hardness for heavy-load applications.

Q: Can these be reused after removal?

A: It is generally recommended to use new washers for critical safety applications. However, if removed carefully without deforming the claws, they can be reused for non-critical tasks.

Q: What specific round nut sizes does this kit cover?

A: This specific listing covers standard metric round nut diameters ranging from M10 to M30. Please check the size chart in the product images for exact dimensions.

Q: Are these washers suitable for outdoor marine environments?

A: Yes, if you select the 304 Stainless Steel option, it offers excellent corrosion resistance suitable for marine and outdoor applications.

Q: Do I need special tools to install these six-claw circlips?

A: While specialized circlip pliers are recommended for ease of installation, a sturdy pair of needle-nose pliers can also be used effectively for most sizes.
