Special Thread Gauges

Special thread gauges are inspection tools used to verify thread form and functional fit when standard gauges are not sufficient. They enable fast, repeatable go/no-go checks in production and quality control, confirming that a thread meets tolerance requirements without time-consuming profile measurement.

This collection covers solutions for non-standard profiles and demanding applications, including metric and inch threads, fine pitches, and threads used in hydraulic/pneumatic components or custom specifications. Options include GO/NO-GO plug and ring gauges designed for high hardness, dimensional stability, and clear identification for traceability. Choose dependable gauges from Johs to support consistent inspection results in shop-floor conditions.

These gauges are widely used by machine shops, QC departments, precision parts manufacturers, and industrial maintenance teams where correct thread engagement is critical for assembly, incoming inspection, and process control.
