Shim Seats

Shim seats come in a wide variety of shapes and sizes. At Maple Industries, Inc., we carry 19 unique series of shim seats to meet our customers' needs. This includes more than 100 individul shim seats. To help you find the part you need, we have listed them in easy-to-read grids that include the series ID, style number, insert I.C., thickness (T) and radius (R).

All of our shim seats are made to exacting standards right in our New Hudson, Michigan facilities and have been for more than 30 years.

In addition to shim seats, we carry a full line of specialty screws and fasteners for the carbine cutting tools industry. Click on any of the links on the left to learn more about our product line.
