Great service from representatives and order arrived on time with no hiccups!
Nuts, bolts and washers were just what I needed to install oar sockets on Puffin. Service deserved ⭐️⭐️⭐️⭐️⭐️⭐️ but apparently five is as many as I’m allowed to award!

Great quality product and terrific customer service
Silicon Bronze Flat Washers
Always a quality product and great customer service.
They are outstanding. Thank you!
I placed an order for a mere 4 bronze lag screws and washers for a project, and, despite the minimal size of the order, Rob was incredibly attentive in filling it promptly. He also offered a wider variety of sizes in bronze than any other soiurce I could find, including the usual marine supply stores. And when it turned out the washers were the wrong size (my fault), Rob graciously sent me the correct size, in two variations, for free. I cannot say enough good things about Rob and his company.
These bronze washers were high quality, just as I was hoping.
