FAQ
Frequently Asked Questions
Does the homepage calculator still contain all tools?
Yes. The homepage keeps the original tolerance calculator, unit switching, precision selection, hole and shaft codes, custom override, fit filter, load advisor, MMC/LMC display, gauge values, probability range, thermal correction, presets, saved configuration, and PNG/PDF export.
Is this a substitute for ISO standards or a certified engineer?
No. The site is an educational engineering reference. Use official standards, qualified review, and supplier process data before releasing safety-critical or regulated designs.
Why does temperature matter?
Materials expand and contract. Even when both parts share a material, temperature can affect absolute size and inspection interpretation. Mixed materials can require deeper review.
How can I report a correction?
Email support@tolerancecalculator.online. This is the only public contact address for the website.
