Acme / Stub-Acme Thread Gauges

Acme Thread Gauges are manufactured as per ASME B1.5, while Stub-Acme Thread Gauge dimensions are manufactured as per ANSI/ASME B1.8. Gauge blanks are manufactured in accordance with the ASME B47.1 standard.

Acme Threads are available in 3 Classes of Fit, with 2G being the most commonly used class. Where reduced backlash is required in Acme threads, 3G and 4G classes are used to provide closer fit and improved control.

• Manufactured in hardened, precision hand-lapped OHNS Steel material to provide superior accuracy, excellent wear resistance, and optimum finish.
• Gauges are also manufactured with customized Thread Pitch, Class, and Tolerances as per specific requirements. The Thread Angle is 29°.
• Subzero treated at -80°C for Dimensional Stability.
• Calibrated at 20°C under Standards Room conditions.
• Gauges are delivered in plastic case, providing anti-corrosion effect and impact resistance with Calibration Certificate (NABL/NPL Accredited).
