Control Ring with Threaded Groove - VLKEL

Usage: The 'N'ENTRE PAS' threaded ring should only be manually screwed (with reasonable effort) into the piece's threading for a maximum of two rotations. If it can be screwed in more than two rotations, the threading does not meet the requirements (thus, 'N'ENTRE PAS'). The 'N'ENTRE PAS' ring should be marked in red. For machined parts and gauges, the reference temperature is 20°C. As the manufacturer, VÖLKEL offers an on-demand factory calibration certificate (price upon request). Calibration is performed in an independent VÖLKEL measurement lab, following specified directives and standards (DIN, ISO, ANSI) for each sample. Calibration is done using an IAC threading scanner.
