Description
The Asimeto Plug Hole Gauge H7 from the 670 Series is a precision instrument built for engineers, machinists, and quality-control professionals who measure cylindrical holes with tight H7 tolerance. Sized specifically for 20 mm bores, it delivers accurate, repeatable readings with a reliable fit between gauge and bore.
- Series: 670 Series — a line of precision hole gauges designed for high-accuracy bore inspection.
- Diameter compatibility: Optimized for 20 mm holes with H7 tolerance, ensuring a close, controlled fit.
- Design: Dual-ended body with a textured central grip and polished ends for easy handling and alignment.
- Accuracy: Precision-machined geometry to maintain stable measurements across repeated checks.
- Applications: Ideal for quality control, machining setups, and assembly verification where bore size matters.
Using this gauge reduces guesswork in hole inspection and helps ensure assemblies fit as designed. The 20 mm H7 specification supports consistent manufacturing tolerances, enabling quicker pass/fail decisions during inline quality checks. Its robust construction and precise geometry translate to fewer rework cycles and more reliable part-to-hole compatibility in tools, jigs, and housings.
