Great bulk price

Can't beat the price for this quantity. Used them on a trailer hitch assembly. They hold up well under heavy load and road vibration.

Good quality, fast shipping

These washers are sturdy and well-made. I used them for a garden gate installation. One star off because the packaging was slightly damaged, but the product inside was fine.

Solid hardware

Bought a mixed pack to keep in the toolbox. The zinc coating seems durable. They work exactly as a spring washer should.

Essential for vibration resistance

I run a small machine shop and go through these quickly. This batch has consistent hardness and the split gap is uniform across all pieces. Highly recommended.

Perfect fit for my project

Ordered the M8 size for a automotive repair. The galvanization looks solid and they fit perfectly without being too tight. Great value for the quantity.

Exactly as described

Needed M5 washers for an electronics enclosure. They provide just the right amount of tension. No rust issues so far after a few months of indoor use.

5 FAQ

Q: Is the material carbon steel or stainless steel?

A: This specific listing is for Carbon Steel with a Zinc Galvanized finish. We also carry a separate Stainless Steel version if you need higher corrosion resistance.

Q: Are these washers suitable for outdoor use?

A: Yes, the galvanized zinc plating provides good corrosion resistance for outdoor applications, though extreme marine environments may require stainless steel.

Q: What is the thickness of the M10 washer?

A: According to DIN 127 standards, the nominal thickness for an M10 split lock washer is approximately 2.5mm.

Q: Can these be reused after removal?

A: While technically possible, it is generally recommended to replace spring washers after removal as they may lose some of their elastic tension.

Q: Do you sell these in individual sizes or only mixed packs?

A: We offer both options. You can select specific sizes like M6 or M10 individually, or choose our assorted kit containing multiple sizes.
