Rotech Rural’s bullet hinges are made up of steel casings surrounding a brass pin and washer. Their greasable hinges include a grease nipple at the top.
The casing is uncoated steel, making it easier to weld than galvanised steel products. Galvanised steel is often difficult to weld due to its thick coating.
You can also choose a greasable hinge. We highly recommended this hinge if you plan to use the hinge often, such as on the tailgate of your ute. Greasing your hinge will make it smoother, and last a lot longer than an ungreasable hinge.
