This Lynch Pin is made from 1010 grade carbon steel, a low carbon steel alloy containing approximately 0.08�0.13% carbon, known for its durability, affordability, and ease of use. Designed with a solid pin and a self-locking ring, it snaps securely into place to hold parts firmly. The pin features a zinc yellow coating, a thin external layer that provides corrosion resistance and gives the part its distinctive yellow tint.
