High-Precision Pin Gauges: Micron-Level Accuracy for Your Critical Inspection
CMC & ISO 9001 Certified. 100% Inspected by German & Swiss Metrology Equipment. Available in Ceramic, Tungsten Carbide, and Steel for 0.001mm Precision.
Introduction & Details
Pain Points & Background
In precision machining, even a 1-micron deviation can lead to the rejection of an entire batch of aerospace components or medical devices. Traditional steel pin gauges are highly prone to wear, corrosion, and measurement deviations caused by environmental temperature changes. As a quality engineer, are you facing challenges such as short gauge lifespan, difficult traceability, or long lead times for non-standard sizes? Mihe Precision (MISHUTE) pin gauge series is designed to provide global manufacturers with stable, reliable, and highly cost-effective solutions for hole diameter measurement.
Core Products & Services
Mihe Precision pin gauges cover a complete size range from 0.1 mm to 30 mm, with increments as fine as 0.001 mm. In addition to offering cost-effective GCr15 bearing steel pin gauges, we focus on the application of high-performance materials. Our zirconia ceramic pin gauges feature excellent chemical and thermal stability, with a service life 5–10 times longer than standard steel gauges. Tungsten carbide pin gauges, on the other hand, provide ultra-high hardness to meet the demands of 100% inspection in high-volume production. All gauges are manufactured in a 20°C constant-temperature laboratory, ensuring peak performance and dimensional accuracy right from delivery.
Key Features
- Ultra-Precision: Tolerance classes available in Class Z, Class X, and Class XX.
- Material Diversity: Options include Zirconia Ceramic, Tungsten Carbide, and Hardened Steel (60-65 HRC).
- Full Traceability: Each set or individual pin is traceable to national standards with available inspection reports.
- Bespoke Sizes: Fast turnaround for non-standard diameters and special lengths.
Material Capabilities

FAQ
Class Z is the most common for general shop use (tolerance .0001″). If you are measuring high-precision parts in a lab environment with tighter tolerances, Class X (.00004″) is recommended for higher reliability.
No. One of the greatest advantages of Zirconia Ceramic is its corrosion resistance. You can handle them with bare hands and store them without messy oil, making them ideal for cleanroom environments.
Yes. We provide customized Go/No-Go members pre-assembled into high-quality aluminum or plastic handles, color-coded (Green/Red) for fast production line sorting.
Each product is shipped with an MISHUTE inspection report. Additionally, our gauges are compatible with international calibration standards, allowing you to verify them at any local ISO 17025 accredited laboratory.
