I Open-Sourced the ISO 286 Fit Tables Behind My Tolerance Tool
Tired of PDF tables, I keep a computed subset of ISO 286-2 in code — limits & fits for the hole-basis combinations that actually show up on drawings: IT5–IT8, shafts f/g/h/k/p, all 13 size bands to 500 mm. Plus ISO 2768-1 general tolerances. Now it's a standalone MIT repo. Three ways to use it: python iso286.py 25 H7/p6 # H7/p6 @ 25 mm [interference] # hole 0 / +0.021 mm # shaft +0.022 / +0.035 mm # clearance -0.035 … -0.001 mm Or the same module in TypeScript, or just fits.json as raw data. ht…
