The C&H Precision plates are designed, manufactured, and shipped from their small family-owned business in Coastal Georgia. Each plate is precision machined to the tightest tolerances on HAAS CNC machines and each plate goes through multiple quality checks before shipping to their customers. Most of C&H's plates feature a patented stainless steel T-Nut which provides an industry-leading six to seven threads of engagement. Since all the mounting hardware is replaceable, if any mounting hardware is damaged it can be replaced without replacing the entire plate.
