The Asimeto Ring Hole Gauge H7, from the 675 Series, is a precision tool designed to verify the diameter of ring-shaped holes with H7 tolerance. Built for machinists, quality inspectors, and manufacturing engineers, it delivers reliable measurements to support tight tolerances in production.

• Nominal size: 8 mm
• Tolerance: H7 tolerance for a close, controlled fit with ring holes
• Series: 675 Series
• Intended use: Precision gauge for measuring the diameter of ring-shaped holes in machined parts, jigs, and fixtures
• Measurement principle: Direct diameter reference that provides quick, repeatable checks on the shop floor

This gauge helps you quickly confirm hole size accuracy, reduces guesswork during assembly, and supports consistent quality control across production runs. Its tight H7 fit is ideal for applications where precise hole diameters are critical, such as bearing seats, gear housings, and aligned assemblies. Use it in setup, inspection, and calibration moments to maintain reliable tolerances and reduce rework.
