Fowler 53-666-503-0 SNAPMATIC 3-4"

The Fowler-Bowers SNAPMATIC snap gage has been designed specifically for quick, reliable and accurate measurement of external cylindrical diameters. Particularly suitable for use in series production, the instrument is tough and solid enough to use on the machine in the workshop and flexible enough to be used in the measuring room for sample measurements. The measuring surfaces are of top-quality tungsten carbide mounted on a non-maintenance apring-operated mechanism. Special anvils (e.g for grooves etc.) can be fitted to the standard gauge by means of the mounting holes in the anvil.
