The C&H Precision plates are designed, manufactured and shipped from our 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 our customers. Plates are made from 6061 aluminum. All mounting hardware is Stainless Steel. Most of our 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.
