Decent but stiff

They work well as lock washers, but they are quite stiff. Had to use extra torque to flatten them out initially. Good for heavy-duty applications though.

Great value for money

You get a lot of washers in this pack. The split design provides excellent locking force. Highly recommend for general DIY repairs.

Perfect for small electronics projects

These M2 and M3 washers are exactly what I needed for my drone build. The nickel plating looks clean and they fit perfectly without slipping.

Essential hardware staple

I keep a box of these in my toolbox. The variety of sizes (M2-M5) in one order is very convenient. No issues with breakage during installation.

Exactly as described

The sizing is accurate. I measured the M5 washers with calipers and they are spot on. The nickel finish prevents rust in my indoor workshop environment.

Good quality, fast shipping

Solid spring tension on these lock washers. I used the M4 size for a garden gate latch. Only giving 4 stars because the bag was slightly torn upon arrival, but the parts were fine.

5 FAQ

Q: Can these be reused after removal?

A: Split lock washers are generally designed for single-use applications as they may lose their spring tension after being compressed and removed. For critical assemblies, we suggest using new washers.

Q: Does this package contain a mix of all sizes or just one size?

A: This specific listing allows you to select a single size (M2, M3, M4, or M5) from the dropdown menu. If you need a mix, please purchase separate quantities for each size.

Q: Are these washers suitable for outdoor use in rainy conditions?

A: While the nickel plating offers some protection, these are best suited for indoor or dry environments. For prolonged outdoor exposure, we recommend stainless steel variants.

Q: Is the material magnetic?

A: Yes, since these are made of carbon steel with a nickel plating, they are magnetic. If you require non-magnetic washers, please look for our brass or stainless steel options.

Q: What is the thickness of the M4 washer?

A: According to DIN 127 standards, the nominal thickness for an M4 split lock washer is approximately 0.8mm, though slight variations may occur due to manufacturing tolerances.
