Description
Gagemaker’s standard contact points are manufactured with carbide balls. Both threaded and straight (non-threaded) shanks are available. All Gagemaker’s inspection gages use threaded shank contact points. Threaded shanks are #4-48 UNF. Metric threads are available upon request. Most gages require two contact points.
