Major diameter: This can be checked by outside micrometers, go/nogo plain ring gages, or snap gages, as well as the Thread Trend System fitted with plain rolls.

Guidance on thread gaging

Through a series of air and mechanical snap gages, dimensional data relative to the flange is measured for d2, d3 gage line diameters, "V" groove location, the depth of the ejection surface, and the location of the L6 clamping angle.

Among the many variations of dial indicators: long-range indicators for measuring table movement or slide travel, dial calipers for quick ID comparisons, pocket thickness gages for quick checks of materials, dial snap gages for ODs up to 12", dial bore gages for three-point contact go/no-go measurements, and back plungers where the mounting stem is on the back for mounting on holding fixtures.

Progress in basic gaging

Statistical analysis for SPC can be based on simple inputs from electronic snap gages, height gages, or any other source, as long as measurements are taken quickly when the parts come off the machine tool.
