Great for DIY furniture assembly

Used the M6 size to secure bolts on an outdoor bench. The zinc coating gives me confidence they will last through the seasons. Highly recommend for home projects.

Reliable supplier for bulk orders

We use these for our automotive sub-assembly line. The Grade 8.8 rating holds up well under vibration tests. Will definitely reorder when stock runs low.

Exactly as described

Needed specific M10 washers that wouldn't rust immediately in our workshop environment. These galvanized ones are working great. No issues with splitting or flattening.

Good quality, fast shipping

Bought a mixed pack of M4 and M5 washers for electronics assembly. Quality is consistent with national standards. Only giving 4 stars because the packaging was slightly crushed, but the washers inside were fine.

Solid spring tension

The elastic recovery on these 65Mn washers is impressive. They maintain pressure well after tightening. Good value for the price compared to local hardware stores.

Perfect fit for my machinery project

Ordered the M8 size for a conveyor belt repair. The galvanization looks even and the steel feels very sturdy. They snapped into place perfectly and provided excellent tension.

5 FAQ

Q: Are these washers suitable for outdoor applications?

A: Yes, the zinc galvanization provides moderate corrosion resistance suitable for general outdoor use. However, for highly corrosive marine environments, stainless steel options might be preferable.

Q: Can I buy individual sizes or only mixed packs?

A: You can purchase individual sizes (e.g., only M8) or select our variety mixed packs. Just choose the specific SKU corresponding to the size you need.

Q: What is the hardness rating of the 65Mn material used?

A: Our 65Mn spring washers are heat-treated to achieve a hardness range of HRC 44-52, ensuring optimal elasticity and durability under load.

Q: What is the maximum temperature these washers can withstand?

A: Standard galvanized spring washers perform well up to approximately 200°C (392°F). Beyond this temperature, the zinc coating may degrade, and the temper of the steel could be affected.

Q: Do you offer a certificate of compliance for Grade 8.8?

A: Yes, we can provide a mill test certificate or compliance document upon request for bulk orders. Please contact our sales team with your order number.
