Reliable supplier

Third time ordering from this listing. Consistency is key for us, and these washers deliver every time. No defects found in the last 500 units used.

Perfect for machinery repair

These washers are exactly what I needed for my lathe maintenance. The nickel plating looks clean and the split tension is consistent across the batch.

Solid washers

They work as expected. The nickel finish helps prevent rust in my garage projects. Would be nice if they came in smaller quantities for hobbyists.

Good quality, fast shipping

Ordered the M6 size for a DIY project. They fit perfectly and seem very durable. Only giving 4 stars because the box was slightly dented on arrival, but the contents were fine.

Great value for money

Bought a mixed pack for my workshop. Having various sizes from M3 to M12 on hand is super convenient. The metal feels solid.

Industrial grade quality

We use these in our assembly line. The Grade 8.8 hardness holds up well under high vibration conditions. Will definitely reorder.

5 FAQ

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

A: We offer both individual size boxes (e.g., M6 only) and mixed assortment kits. Please select your preferred option from the dropdown menu.

Q: Is the nickel plating RoHS compliant?

A: Yes, all our nickel-plated fasteners comply with RoHS standards and are safe for general industrial and consumer applications.

Q: What is the exact hardness rating?

A: These Grade 8.8 washers typically have a hardness range of HRC 42 to 50, ensuring excellent spring tension and durability.

Q: Are these washers suitable for outdoor use?

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

Q: Can these be reused after removal?

A: Spring washers are generally designed for single-use to ensure optimal locking force. However, for low-vibration applications, careful reuse may be acceptable if the washer retains its shape.
