Meyer Gage 0.279mm to 25.645mm Class X Custom Length Heat Treated Gage Pins (Metric)

Meyer Gage 0.279mm to 25.645mm Class X Custom Length Heat Treated Gage Pins (Metric)

Meyer Gage Class X Custom Length Heat Treated Gage Pins are designed for demanding inspection environments that require extended reach without compromising dimensional accuracy. These metric pins are available in custom lengths from 3" to 6" and are manufactured to precise Class X tolerances, making them ideal for calibration, inspection setups, or when space and depth require longer gage tools.

Each pin is made from premium 52100 steel and heat treated to 60–62 Rockwell C for excellent wear resistance and long-term stability. Diameters above 12.70mm (0.500") are cold stabilized to enhance accuracy in temperature-variable environments. For traceability and confidence in quality, all pins above 1.51mm (0.060") are laser marked with the size and tolerance direction, and each piece is assigned a unique serial number.

These metric Class X Custom Length Heat Treated Gage Pins are available in GO (Plus), NOGO (Minus), or Bilateral (Split) tolerance directions, supporting a wide range of inspection routines. If your application requires dimensions outside the 3"–6" range, custom lengths and assemblies are available upon request.

Available Custom Length Ranges by Diameter:

• 0.279mm to 25.645mm (Metric sizes)
• Class X pins available in 3" to 6" lengths
• Custom lengths under 3" or over 6" available by quote
