Feature

UNC, UNF, or UNEF if the diameter-pitch combination is from the “Coarse,” “Fine,” or “Extra Fine” series and may be followed by a tolerance level. Example: #6-32 UNC 2B (Major Diameter: 0.1380 in. Pitch : 32 tpi) Unified Screw Threads – UNC, UNF and UNEF

A wide selection of GO/NO-GO fixed gauges are available for checking internal and external thread diameters to ensure accuracy during the machining process. This ensures a “nice fit” between the threaded components, thereby loosening the screw-mounted joints in your final piece.

What is threaded plug inspection?

• GO threaded plugs check minimum core diameter, minimum pitch diameter in any section.
• NO-GO gage threaded plug Verify that the hole does not exceed the maximum pitch diameter in any section.
