Small Diameter UN - UNJ & UNR Series Thread Rolls

Small Diameter Internal UN, UNJ, & UNR Series Functional Size/Pitch Diameter Inspection – (⅝” (.625″) to 1½” (1.500″) Diameters)

Thread Check Inc. offers a Gagemaker solution for smaller internal UN, UNJ, & UNR Series thread diameters.

Pitch diameter and functional size inspections are critical for every threaded connection. This can be especially true in smaller diameters, but these smaller diameters require a unique gage design to perform the proper inspections.

The Gagemaker SPG-6000 Series of thread inspection gages measures internal  functional size and pitch diameter of Acme thread diameters between .625″ and 1.500″. The SPG-6000 can be equipped with either thread rolls or contact points to measure ACME, Stub Acme, Stub ACME Modified-1 & -2, Metric, MJ, UN, UNJ, & UNR Series of threads. The SPG-6000 Series is ideal for threads with special P.D.s or pre-plate requirements.

For thread functional size inspection, thread rolls attach directly to the gage. 

The SPG-6000 can be set using our MIC TRAC™ gage setting systems, rod standards, calipers, gauge blocks, or micrometers. For best results, Gagemaker recommends our MIC TRAC™gage setting systems or rod standards. For gage setting dimensions regardless of setting method or selecting additional contact points, our helpful, easy-to-use TDWIN™thread engineering software program may be required.

Contact points, contact point arm sets, thread roll sets, gage setting devices, and software are all sold separately

Thread Check has a team of technical experts that are ready to help you with all your gauging and measurement requirements. Contact us via email at info@threadcheck.com or call us at 800 767 7633
