Solid industrial grade washers

Using these for outdoor fencing projects. They seem very durable and haven't shown any signs of rust after a few weeks of exposure to rain. Would recommend for outdoor use.

Great assortment for the home workshop

Bought a mixed pack to keep in my toolbox. Having M2 through M12 on hand saves so many trips to the hardware store. The finish is smooth and professional.

Exactly what I needed

Precise dimensions matching the GB93 standard. I verified the M12 size with calipers, and it was spot on. Will definitely order again for future manufacturing runs.

Perfect fit for my machinery repairs

Ordered the M8 and M10 sizes for some agricultural equipment maintenance. The steel quality feels solid, and they fit perfectly without any binding. Great value for the quantity received.

Essential for vibration-heavy applications

I run a small auto repair shop and go through these quickly. The 304 stainless holds up well against oil and grease. The spring tension is consistent across the batch I received.

Good quality, fast shipping

These washers are exactly as described. I used the M4 and M5 sizes for an electronics enclosure project. One star off only because the packaging was slightly crushed, but the product inside was fine.
