Precision GO Thread Plug Gauge Tol. 2B UNC 2.1/4 x 4.5

Calibration Certificate for Thread Gauges In a measurement laboratory independent of VÖLKEL's production, the calibration is carried out according to the defined specifications and standards (DIN, ISO, ANSI) for the respective test object. The calibration is performed using IAC thread scanners. Important Notes: The calibration and the certificate can only be ordered together with a thread gauge One certificate is required per each thread gauge. If multiple gauges are ordered, the number of certificates must be adjusted accordingly Issuing multiple certificates for a single thread gauge is not possible The dimensions of the following thread ring gauges cannot be calibrated, and therefore, no certificate can be issued: Metric / Metric fine: ≤ M 3 and UNC / UNF: ≤ No. 6 Processing time: approx. 1-3 business days (shipping will be extended accordingly)
