A steel offset carabiner is a type of offset carabiner that is made from steel. As mentioned earlier, an offset carabiner has an asymmetrical shape, with one end of the carabiner wider than the other. This shape is designed to allow the carabiner to sit flush against a surface, such as a bolt hanger or piton, while still allowing a rope or other equipment to be clipped into the carabiner.

Steel offset carabiners are often preferred for their durability and strength. They are commonly used in aid climbing, where climbers use gear to help them ascend a route. They are often used to connect aiders, etriers, or daisy chains to anchor points, or to connect gear such as nuts or cams to the climbing rope.

Steel offset carabiners come in a range of sizes and strengths, and can be selected based on the specific needs of the climber and the climbing route. It's important to inspect your steel offset carabiners regularly for signs of wear or damage and to retire them immediately if they show any signs of weakness.

When selecting a steel offset carabiner, it's important to consider factors such as weight, strength, and compatibility with other gear. It's also important to choose a reputable and reliable supplier that offers high-quality products.
