Reliable and durable

Third time ordering these. Consistency in quality is impressive. The saddle shape distributes pressure evenly, protecting the underlying surface.

Great value for bulk purchase

Bought the M8 variety pack for our workshop. The hardness is consistent across all pieces, and the price point is very competitive compared to local suppliers.

Good quality, fast shipping

The steel feels robust and the black oxide coating is even. I ordered M12 size and they fit perfectly. Only giving 4 stars because the packaging was slightly crushed.

Solid product for railway applications

We use these for rail fastening systems. They hold up well under stress. Would prefer if they came with a zinc plating option for outdoor use, but overall satisfied.

Perfect for heavy machinery maintenance

These 65Mn washers are exactly what I needed for securing bolts on our conveyor system. The claw design grips well and prevents loosening under vibration.

Excellent anti-slip performance

Used these on a structural project where slip resistance was critical. They performed flawlessly during load testing. Highly recommend for industrial use.

5 FAQ

Q: What is the maximum temperature these 65Mn springs can withstand?

A: 65Mn spring steel generally maintains its mechanical properties up to approximately 120°C (248°F). Beyond this temperature, tempering may occur, potentially reducing the spring's tension and effectiveness.

Q: Are these washers suitable for outdoor exposure to rain?

A: These washers feature a black oxide coating which offers moderate corrosion resistance. For prolonged outdoor exposure to moisture, we recommend applying an additional rust-inhibiting grease or selecting a zinc-plated variant if available.

Q: Can I mix sizes in one order?

A: This listing allows you to select a specific size range from the dropdown menu. To order multiple different sizes, please place separate orders for each size required or contact our sales team for a custom bulk invoice.

Q: Do you offer these in stainless steel?

A: Currently, this specific listing is for 65Mn Carbon Steel only. We do carry stainless steel disc springs in a separate product category. Please search our store for 'Stainless Steel Claw Washers' for those options.

Q: Is there a certificate of material compliance included?

A: Yes, for bulk orders over 50 packs, we can provide a Mill Test Certificate (MTC) upon request at checkout. For smaller quantities, standard quality assurance documentation is available via email after purchase.
