External Functional Size Thread Inspection Gages

Thread Check Inc. offers a full range of Gagemaker RG Series external thread functional size inspection instruments. 

Functional thread gauging inspects the cumulative effects of the thread elements including diameter, lead, taper, flank angle and form error. Gagemaker RG external functional inspection gages provide the same functionality of thread rings with the added benefits of accurately measuring thread size within wide range of diameter and thread pitch sizes.

Functional thread inspection gages measure thread diameters. These functional measuring instruments are adjustable within a wide size range 5/8 up to 24 inches for external sizes. They use interchangeable thread rolls to measure different pitch threads including 60 degree unified, metric, Acme, Stub Acme, Buttress, and trapezoid. Extension arms and handles are available for extra reach requirements. Hand held portability allows the user to measure thread size while the part is still on the machine.

The Gagemaker RG Series thread functional size inspection instrument is accurate, versatile, and economical.

Master Gages are not required. The RG and PG Series thread measuring instruments can be set with gage blocks, rod standards or other types of setting equipment including the MIC TRAC Gage Setting System (MT-3000). Setting dimensions for the functional pitch diameter gages are provided by the TDWIN Thread Disk software. 

Indicators have a .5" travel and .0005" resolution with higher resolutions available.

Thread roll sets not included. The software and thread rolls are sold separately.

The Gagemaker PG and RG thread functional size inspection instrument is accurate, versatile, and economical.
