INSIZE 4267-13D Steel Pin Gauge Set (High Accuracy) Ø13.00–13.50mm

INSIZE's 4267-13D is a 51-piece steel pin gauge set covering Ø13.00–13.50mm in 0.01 mm steps, letting a user check hole and slot sizes across that range in fine increments. The pins are made from alloy steel, hardened to HRC62-65 and held to ±0.5 µm diameter accuracy, meeting the DIN 2269 grade 0 standard for pin gauges. Sets like this suit tool rooms and calibration labs, where they verify bore diameters and set other measuring instruments against a precise, traceable size step.
