Since Compac dial bore gages have been discontinued, spare parts are limited. We are reserving them for our own repairs.
Replacement contacts are only available for sale while supply lasts. Please send us an email for current stock and pricing.
How it works: the larger value is when the contact is used with Extension R; the lower value when it is used without the extension.
Note: contacts for this bore gage have metric M3 threads.
