🎯 Tolerance & Fit Calculator

Instantly calculate upper and lower limits, max clearance, and interference for standard engineering fits.

Nominal Size (mm)

Note: This demo tool uses fixed tolerance values optimized for the 10-30mm range.

Fit Designation

Clearance

Parts can move and slide freely. Used for clutches, gear spigots.
