## Summary description

FANAR thread plug gauge M20 x 1.5 (S3-302161-0205) is a go/no-go inspection tool designed for checking internal metric threads with 20 mm diameter and 1.5 mm pitch. It provides a straightforward pass/fail verification of thread conformity to specified dimensions, useful in production, quality control, and maintenance for fast, repeatable checks of threaded holes and components.

## Long description

FANAR thread plug gauge M20 x 1.5 is a go/no-go inspection tool intended for verifying internal metric threads with a nominal diameter of 20 mm and a 1.5 mm pitch. The gauge provides quick, repeatable pass/fail checks to determine whether threaded holes and internal threads conform to the required dimensional tolerances. It is manufactured for direct use in production, incoming inspection, and maintenance workflows where simple and reliable thread verification is needed.
Advantages
The gauge offers immediate go/no-go results without the need for measurement calculation, reducing inspection time and operator interpretation. Made according to standardized thread tolerances, it ensures consistent verification across multiple parts and operators. The compact, hand-held design is suitable for on-machine and bench inspections, enabling fast assessment of internal threads with minimal setup.
Suitable for
 Production line thread checks on components with M20 x 1.5 internal threads
 Incoming inspection of fasteners, housings and machined parts
 Maintenance and repair tasks requiring quick thread conformity verification
 Quality control sampling and shop-floor acceptance tests
Key specifications
 Thread form: metric ISO thread profile
 Nominal diameter: 20 mm
 Thread pitch: 1.5 mm
 Type: go/no-go plug gauge for internal threads
 Material: hardened steel suitable for repeated inspection use
 Finish: precision-ground surfaces for accurate engagement
How to use
Insert the go end of the plug gauge into the internal thread to confirm the thread meets minimum acceptable limits; it should engage smoothly without excessive play. Use the no-go end to check that the thread does not exceed maximum material limits; the no-go end should not thread fully into the hole. Perform inspections with clean threads and avoid forcing the gauge to prevent false readings. Record results as pass if the go end fits and the no-go end does not, otherwise mark the part as nonconforming.
Usage recommendations
Ensure threads are free of burrs, chips and lubricants before inspection. Store the gauge in a protective case and verify condition periodically; replace the gauge if wear affects fit. Use proper lighting and, when necessary, magnification to confirm engagement. For critical applications, complement plug gauge checks with full dimensional measurement to document thread geometry.
