Meyer Gage Class X MG-25 MINUS Steel Gage Pin Sets (Metric)

Meyer Gage Class X MG-25 MINUS Steel Gage Pin Sets (Metric)

The Meyer Gage Class X MG-25 MINUS Steel Gage Pin Sets (Metric) are precision-crafted metrology tools designed for high-accuracy dimensional verification around a specific nominal size. These sets include 25 gage pins—12 incrementally smaller and 12 incrementally larger than the nominal diameter—offered in 0.01mm steps, making them ideal for applications requiring tight tolerance control and NOGO inspections.

Manufactured to Class X tolerance (±0.00102mm or 0.000040”), these metric pin gage sets ensure exacting dimensional compliance for hole size validation, micrometer calibration, part inspection, and more. Each pin is 2" long, made from heat-treated 52100 bearing steel, and finished to 4 microinch or better for long-term durability and performance.

MG-25 MINUS sets are organized in rugged storage boxes (MG SET-RT) with each gage laser-etched with size and serial number for traceability (except for the smallest sizes). With traceability to NIST and a tolerance limit far tighter than Class ZZ or Z, these sets are trusted by professionals in manufacturing, aerospace, and quality control labs worldwide.
