Gauge Block & Parallel Gauge Blocks made of Special Steel | ULTRA Shop

Buy high-quality reference and working standards made of special steel as individual parallel gauge blocks or as a complete gauge block set according to DIN EN ISO 3650.

Gauge blocks made of specially hardened and stabilized steel form the reliable foundation for precise measuring results in your production. These high-precision material measures for length serve as indispensable reference and working standards for calibrating measuring instruments, accurate workshop measurements, and demanding applications in quality assurance. Depending on the environment in your workshop, production floor, or testing laboratory, you can choose from four precise tolerance classes (Grade 0, 1, 2, and calibration grade K). Each individual gauge block is delivered permanently engraved with its exact nominal size and a unique identification number. Larger dimensions from 125 mm upwards are equipped with practical holes for gauge block connectors as standard.

Our parallel gauge block sets in protective wooden cases with clear layouts include compositions from 6 to 122 pieces, covering all requirements of professional length metrology. Special complementary sets such as angle gauge blocks or sets including optical flats for visual flatness testing complete the product line for versatile inspection applications. All special steel gauge blocks ensure seamless and traceable connection to national standards through optional DAkkS calibration certificates or factory calibration certificates.
