HFS 36 PC Gauge Block Set Economy Grade Calibration NIST-Traceable

Key features

• Complete 36-Piece Inch Set: Includes 9 blocks from .1001" to .1009", 9 from .101" to .109", 9 from .110" to .190", 4 from .200" to .500", plus .050", .100", 1.000", 2.000", and 4.000" blocks for versatile measuring, setup, and inspection work. Economy accuracy ensures measurements with a tolerance of +/- 0.000050".
• NIST Traceable and ASME Compliant: Includes a Certificate of Calibration and Traceability. Accuracy is verified against master standards traceable to the National Institute of Standards and Technology (NIST). The gauge blocks meet applicable requirements of ASME B89.1.9-2023, and the calibration system used for measurement equipment complies with ISO/IEC 17025 requirements.
• Premium Material and Build: Crafted from fully seasoned alloy tool steel and hardened to 65 HRC for extended service life, excellent wear resistance, and dimensional stability. Built for repeated use in machine shops, inspection rooms, and precision measurement applications.
• Individually Serialized and Calibrated: Each gauge block is marked with a serial number, with its nominal size and measured deviation documented on the included Certificate of Calibration and Traceability for clear identification, verification, and traceability.
• For Machining, Calibration and Dimensional Inspection: Ideal for machine setup, dimensional calibration and inspection, micrometer verification, fixture calibration, toolroom work, quality control, and general metrology applications. Calibration measurements are performed at the standard reference temperature of 68°F (20°C).
