INSIZE 4267-17D Steel Pin Gauge Set (High Accuracy) Ø17.00–17.50mm

The 4267-17D set from INSIZE packs 51 steel pin gauges covering Ø17.00–17.50mm in 0.01 mm steps, so bore and slot sizes across that band can be checked in fine increments. INSIZE hardens the pins to HRC62-65 alloy steel and finishes them to ±0.5 µm diameter accuracy, in line with the DIN 2269 grade 0 standard for pin gauges. Such sets are used in tool rooms and calibration labs to verify hole diameters and to set other measuring instruments where a precise, traceable step size matters.
