What you can do (ISO 286 limits & fits)
• Calculate hole and shaft limit sizes (min/max) from a nominal size and fit designation (e.g., H7/g6, H6/h5, F6/f6).
• See minimum and maximum clearance (or interference) instantly.
• Classify the fit type automatically: clearance, transition, or interference.
• Compare multiple fits quickly while iterating designs or checking drawings.
Typical use cases
• Mechanical design: validate tolerances before releasing drawings and avoid costly rework.
• Machining & tooling: quick shop-floor checks for hole limits, shaft limits, and expected clearance.
• Metrology & inspection: verify parts against ISO 286 limits during incoming/outgoing QC.
• Education & reference: learn how ISO fits behave across sizes and tolerance grades.
Why MetroX
• Fast: minimal inputs, instant results.
• Practical: focuses on the numbers you actually need (limits + clearance/interference).
• Reliable workflow: forward calculation + reverse fit selection.
FAQ
