Series 300P snap gauges can be configured with a number of different indicators and all are fully adjustable with positive position locking at any point within the gauging range.

"Snap gauges are one of the easiest, fastest, most accurate, and economical ways of making OD measurements a shop can employ," says George Schuetz, director of gauges for Mahr Federal. "They are very versatile. They can be hand held to measure parts in place, or mounted on bench stands. They can be set up for any number of readout configurations. Different anvil styles adapt to a host of measurement conditions. And parts literally snap into place, which assures good part 

alignment, and along with positive position locking, virtually eliminates 

influence on the measurement."
