Precision Pin Gauge Set for Metric Inspection
The Vermont Gage 902400200 provides 185 individual pin gauges covering a metric diameter range of 1.31 mm to 4.99 mm in 0.02 mm increments. Made from tool steel hardened to RC 60/65, each pin is a No-Go (Minus) gauge with a tolerance of 0.0002 in to ZZ class. A black oxide finish adds corrosion resistance. An ISO 17025:2005 certification is included.
Tolerance Class Limits Fit-Check Resolution
The ZZ tolerance class and 0.0002 in limit define the practical resolution for pass/fail decisions on hole sizes. The 0.02 mm step between pins means a measured feature can fall between two adjacent gauges, leaving a small uncertainty band. No long-form calibration certificate is supplied, so traceability rests on the included ISO 17025:2005 statement alone.
Simple Hand-Use Setup With Handling Care
Each pin measures 2 in overall length, allowing direct hand insertion into bores or fixtures without special holders. The black oxide surface is uncoated beyond the oxide layer, so clean, dry handling prevents rust and preserves the certified tolerance. Misidentifying a pin because of the dense 0.02 mm spacing is the most common error during rapid inspection.

Questions about this item
How do I decide whether the 1.31–4.99 mm range with 0.02 mm steps covers the sizes I need?
The set contains 185 individual pins spanning 1.31 mm to 4.99 mm in 0.02 mm increments, so every nominal size in that interval is represented by a single no-go gauge.
What does the 0.0002 in tolerance mean when I use a pin in the workshop?
Each pin’s diameter is held within ±0.0002 in of its marked size, giving you a reliable no-go limit for checking hole diameters at the ZZ tolerance class.
Which standard governs the calibration of these gauges?
The set is calibrated to ISO 17025:2005 and includes a certification document, but no long-form calibration certificate is supplied.
