Precision Gauge Products
From standard plug gauges to highly specialized custom solutions, Merc Technologies manufactures precision gauges for dimensional inspection across all industries. Every gauge is manufactured to exacting tolerances and 100% inspected.
Standard Plain Gauges
Our standard plain gauge line covers the most common dimensional inspection needs. All gauges manufactured to ASME B89.1.5 standards with Class X, XX, or XXX tolerances.
Plain Plug Gauges
- Sizes: 0.059" to 12.000"
- GO/NO-GO or progressive styles
- Tool steel or carbide
- Tolerance classes: X, XX, XXX
Plain Ring Gauges
- Sizes: 0.059" to 12.000"
- GO/NO-GO sets available
- Chrome plated or carbide faced

Snap Gauges
- Sizes: 0.100" to 12.000"
- Adjustable or fixed anvils
- Carbide contact points
- Progressive or GO/NO-GO
Thread Gauges
Complete line of thread gauges for all common thread forms. Manufactured to exact specifications with full certification documentation.
Available Thread Forms

Thread Plug Gauges
Precision ground thread gauges for internal thread inspection
Thread Ring Gauges
External thread verification with full certification
Carbide Gauges
For high-volume production environments, carbide gauges offer superior wear resistance and extended service life. Our carbide gauges maintain accuracy through millions of inspection cycles.
Carbide Advantages
- Extended Service Life: 10-20x longer than tool steel in high-volume applications
- Dimensional Stability: Minimal wear ensures consistent measurements over time
- Cost Effective: Lower cost-per-inspection in production environments
- Size Range: Available from 0.010" to 12.000" diameter
