Good value for bulk orders

Bought a large quantity of M6 washers. Most are perfect, though a few had minor surface scratches. Overall, great value for the price.

Exactly as described

Needed specific sizes for a custom repair job. The range from M1.6 to M52 available here saved me from ordering from multiple vendors.

Solid product

The M20 washers are sturdy and hold tension well. Delivery took a day longer than expected, but the product quality makes up for it.
