Gagemaker manufactures a variety of contact points, from traditional ball contacts to roller contacts to blade contacts. Our standard ball contact points are made 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. Custom sizes or designs are available.
