Precision Threading Die - BSP G 2.1/4 x 11 (Tolerance A) by VLKEL

The thread gauge ring must screw onto the thread of the work piece by hand, without excessive force, along its entire length. If this is not possible, the thread does not meet the required standards (rejected). The reference temperature for the work pieces and gauges is 20°C. Upon request, VÖLKEL can provide a factory calibration certificate (price on inquiry). Calibration is performed in an independent testing laboratory, following the specified standards (DIN, ISO, ANSI) for the respective test item, using IAC thread scanners.
