Precision Threading Die - M18 x 2.5 (Tolerance 6g) by VLKEL

The thread ring must be manually screwed onto the entire length of the thread on the work piece without excessive force. If this is not possible, the thread does not meet the desired standards (rejected). The reference temperature for the work pieces and gauges is 20°C. Upon request, VÖLKEL can provide a factory calibration certificate. The calibration is performed in an independent laboratory following the specified standards (DIN, ISO, ANSI) on IAC thread scanners.
