Weld-on hinge / steel pin and brass ring / 120x16 mm / plain steel Simple but effective. That characterizes these steel weld-on hinges with a convex head. The ring is made of the self-lubricating metal brass. This ring protects the steel pin and thus guarantees a smooth, long-lasting turning action. Due to the varying dimensions, these welding hinges can be used on various steel constructions, for example consumables or machines. The big advantage of a weld-on hinge is that the door, window or hatch can be opened completely 180°, which gives you the space to create a free passage. You can easily attach a hinge because the pin part and hole part can be welded separately. This way you will experience more ease of working before hanging the door, window or shutter in its entirety.
