Thread Measuring Pin

Thread Measuring Pin / Master Pins are precision reference gauges designed for the accurate measurement, calibration, and verification of internal diameters, thread dimensions, center distances, and precision bores. Manufactured from premium-grade EN31, Tool Steel, Carbide, or Tungsten Carbide, these master pins are hardened, stabilized, precision ground, and lapped to achieve exceptional dimensional accuracy, superior wear resistance, and excellent long-term dimensional stability. They are widely used as master standards for setting measuring instruments and performing high-precision inspections.

Manufactured in accordance with ISO, DIN, ANSI, ASME, BS, IS, and customer-specific specifications, Thread Measuring Pin are extensively used in automotive, aerospace, bearing manufacturing, mold and die industries, calibration laboratories, metrology departments, precision machining, and quality control facilities. Available in metric and inch sizes with customized diameters, tolerance grades, lengths, and calibration certificates, these master pins ensure reliable calibration, repeatable measurements, and compliance with international quality standards.
