The CH series includes heat-treated carbon steel with zinc clear finish, CHN non-heat-treated carbon steel, CHS passivated 300-series stainless steel and CHA 2024-T4 aluminium. Installed into prepared holes by squeezing force, these pins provide accurate location, reliable retention and efficient assembly without welding, threading or secondary fastening hardware
