Exactly as described

No complaints here. The 8.8 grade specification is accurate, and they work perfectly with high-tensile bolts. Highly recommend for anyone needing reliable locking washers.

Excellent quality for the price

These washers are exactly what I needed for my machinery repair project. The galvanization looks even, and they feel very sturdy. The heat treatment gives them the right amount of spring without being brittle.

Good fit, fast shipping

Ordered the M8 size for an automotive application. They fit perfectly under the bolt heads. One star off only because the packaging was a bit flimsy, but the product itself is great.

Perfect for DIY projects

Used these for securing a heavy shelf to the wall. The zinc coating gives me peace of mind against rust in my garage. Very satisfied with the hardness and durability.

Solid construction

The washers are consistent in size and thickness. I tested the M12 size and it provided excellent tension. Good value for bulk purchasing.

Professional grade hardware

I run a small fabrication shop and we go through a lot of lock washers. These 65Mn steel washers hold up well under vibration. Will definitely reorder when we run low.

5 FAQ

Q: Can I use these with stainless steel bolts?

A: Yes, you can use them with stainless steel bolts, but please be aware that using carbon steel washers with stainless bolts may lead to galvanic corrosion over time in wet conditions.

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

A: The 65Mn steel is heat-treated to achieve a hardness range typically between 44-51 HRC, ensuring high elasticity and resistance to deformation.

Q: Do these come in a pack of mixed sizes?

A: No, each package contains a single specific size (e.g., all M6 or all M10). Please select the required size from the dropdown menu before adding to your cart.

Q: Are these washers suitable for outdoor use?

A: While they are galvanized for corrosion resistance, they are best suited for indoor or general environments. For harsh marine or chemical environments, we recommend stainless steel alternatives.

Q: Is there a bulk discount available for orders over 1000 pieces?

A: Yes, we offer tiered pricing for bulk orders. Please contact our sales team directly or add the desired quantity to your cart to see the automatic discount applied at checkout.
