Carbon Steel (Dowel Pins)
Carbon steel dowel pins are high-strength fastening components widely used in mechanical assembly and precision alignment. They offer excellent hardness and wear resistance, making them ideal for applications requiring accurate positioning and secure fixation. These pins are typically used with pre-drilled holes to ensure repeatable assembly and stable shear resistance.
