Perfect for heavy machinery repair

These washers are significantly thicker than standard ones. I used them on a vibrating motor assembly and they held up perfectly without flattening out. The black finish also provides decent corrosion resistance.

Good quality, fast shipping

Ordered the M8 size for a project. The steel feels very solid and the split is clean. Took off one star only because the packaging was a bit greasy, but the product itself is excellent.

Reliable for high-vibration environments

Used these on a generator mount. The elasticity is spot on, and they haven't loosened after weeks of continuous operation. Great value for the price.

Best washers for the price

Bought a mix of sizes for my workshop. The thickened design makes a real difference when torquing down bolts. No stripping or deformation observed.

True Grade 8.8 strength

I work in automotive restoration and need reliable lock washers. These thickened versions provide much better tension than the cheap hardware store variety. Will definitely buy again.

Solid industrial grade

Very sturdy washers. The black coating seems durable. I wish they offered a larger count pack for M6, but overall satisfied with the quality.

5 FAQ

Q: Is the material magnetic?

A: Yes, since these washers are made from carbon steel (Grade 8.8), they are magnetic.

Q: Are these washers suitable for outdoor use?

A: Yes, the blackened oxide coating offers basic corrosion resistance. However, for harsh marine environments, we recommend applying an additional sealant or using stainless steel alternatives.

Q: Can these be reused after removal?

A: While Grade 8.8 steel is durable, spring washers are generally designed for single-use to ensure optimal locking tension. Reusing them may result in reduced effectiveness against vibration.

Q: What is the exact thickness of the M10 washer?

A: The M10 thickened spring washer has a cross-section thickness of approximately 3.2mm, which is greater than the standard DIN 127 specification.

Q: Do you provide VAT invoices for bulk orders?

A: Yes, as stated in the product description, we provide valid VAT invoices for all orders. Please ensure your company details are entered correctly at checkout.
