Zone U-bolts are protected with a durable black e-coat finish*. The electro-coating protects your U-bolts from the elements. High nuts and heavy-duty washers are included. U-bolts are sold as a set of 4 so you can order any quantity for your project.
Some Zone u-bolts are protected with yellow zinc rather than e-coated. If this matters to you, please contact us prior to placing your order to check on availability of your desired coating.
