Excellent shims

Using these as shims to level some machinery legs. The flatness is consistent across the batch, and the galvanization prevents rust in our humid workshop.

Solid construction hardware

Very sturdy washers. I used the M20 size for a fence post installation. Only giving 4 stars because the packaging was a bit battered, but the product itself is fine.

Exactly as described

The description mentioned 'thickened' and 'widened', and that is accurate. These are much more substantial than the cheap ones found at local hardware stores.

Perfect for heavy-duty repairs

These oversized washers are exactly what I needed for my trailer hitch repair. The galvanized coating looks thick and durable, and the widened surface distributes pressure perfectly.

Great value for money

You get a lot of washers for the price. The oversized design helps prevent pull-through on softer materials like wood. Highly recommend for DIY enthusiasts.

Good quality, fast shipping

Bought the M12 size for a garden structure project. They are slightly thicker than standard washers which is great. Arrived quickly with free shipping as promised.
