Mitutoyo Spare Parts Micrometers and Digimatic digital micrometers
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.
While we stock all the items commonly used for repairs we can't possibly list all of them here. However, a couple of items are on the most frequently requested list. See if what you're looking for is here.
Detailed parts breakdowns and parts lists are available for most models for a nominal fee. You will receive PDF copies by e-mail or download. Click on the linked model numbers for this new service. From these lists it will be easy to identify and order the correct parts.
If you email us a request for specific parts, be sure to include the model number of the Mitutoyo gage. Most Mitutoyo tools have hyphenated numbers such as 505-123, which they refer to as "code number". Include the manufactuer's part number if you have it, or be as descriptive as possible. For example: "the small, black, plastic, rectangular piece with two little plugs sticking out one side... etc."
Be advised that we can not offer refunds for parts you may have ordered in error.
Be aware of model numbers!
As Mitutoyo gages, calipers and micrometers evolve, the manufacturer adds new suffixes such as -20, -N or -S. This little detail must not be overlooked when ordering parts. The model number is always printed somewhere on Mitutoyo gages, if not on the dial.
