0-Grade 3-Pin Gauge External Thread Middle Diameter Pin Gauge Tool 0.118-0.572

Features:

1) Three-needle (gauge needle) use: indirect way to measure the middle diameter of external thread.

2) Three-needle (gauge needle) inspection environment: standard temperature 20°C ± .

3) Measuring for surface hardness: less than 0.72mm = 56-60HRC; greater than 0.72mm = 58-65HRC

4) Accuracy level: Level 0 (±0.00025). Level 1 (±0.0005)

Measurement of the middle diameter of external thread;

Three-needle (gauge needle) for thread measurement: D 0.118~6.585mm

Implementation standard: GBIT22522-2008

Accuracy: Level 0 (±0.00025),

convenient, stable structure, high for .

for mm: ±0.25um

(1) Dimensional deviation of diameter d: Level 0: ±0.25um; Level 1: ±0.50um.

(2) After each use, it is necessary to re-antirust and install it to prevent rust.

(3) When calibrating high- for  measurements, it should be kept at a constant temperature of 20℃ for more than 2 hours.
