Mitutoyo does not sell parts directly to end users. It will be necessary to place your order through a dealer such as Long Island Indicator Service. Be advised that we can not offer refunds for parts you may have ordered in error, but we will issue "store" credit for returns.
Important! Models made after 2016 will have -10 or -16 as a suffix. The parts are different and not interchangeable.
You can ignore any alphabetic letters at the end of model numbers. 513-442T uses the same parts as 513-442.
