Great for outdoor projects

Used these for a deck build near the coast. The galvanization looks thick and uniform. No signs of rust after three months of exposure to salt air.

No rust yet

Been outside for 6 months on a garden structure. Still looking shiny and new. Much better than the zinc-plated ones I used before.

Sizes accurate

Fit my bolts well. The oversized options are truly oversized which helped with some slotted holes I had to work with. Shipping was a bit slow.

Good quality but heavy

The washers are very sturdy and the coating is excellent. They are slightly heavier than standard washers due to the thickening, which is good for stability.

Bulk order perfect

Ordered 50kg for a commercial site. Consistency across the batch was impressive. Fits our standard bolts without any threading issues.

5 FAQ

Q: Is there a minimum order quantity for wholesale?

A: There is no strict minimum order quantity, but bulk discounts apply automatically at checkout for orders over 20kg.

Q: Are these washers completely rust proof?

A: They are highly corrosion resistant due to the hot-dip galvanization, suitable for outdoor use, but extreme conditions may eventually cause wear over many years.

Q: Do you sell matching hot-dip galvanized nuts?

A: Yes, we offer compatible hot-galvanized nuts in the same product listing options. Please select the nut variant when ordering.

Q: What is the exact thickness of the oversized washers?

A: The thickness varies by diameter. For M10 oversized, it is approximately 3mm. Please refer to the detailed specification chart in the product images.

Q: Can I use these for marine applications?

A: Yes, hot-dip galvanized fasteners are recommended for marine environments due to their superior zinc coating compared to electro-plated options.
