If you downloaded the Excel tool above, here is a quick primer on how to get the most out of it.
Tolerance data is useless without knowing your nominal size. For example, a 50mm shaft with an h6 tolerance is different from a 120mm shaft with an h6 tolerance. Always locate the row corresponding to your basic size range (e.g., 30-50mm, 50-80mm).
Modern manufacturing uses plastics, ceramics, and composites alongside metals. Traditional ISO fits assume steel-on-steel interactions. "New" tolerance guides often include adjustment factors for thermal expansion—critical if you are pressing a steel bearing into an aluminum housing. If you use standard steel data for an aluminum housing, your interference fit might loosen up disastrously when the assembly heats up. tolerance data free download link new

We have solved these problems. Below is the link to a clean, new PDF dataset compiled from the latest ISO standards, formatted for print and mobile viewing. If you downloaded the Excel tool above, here
If you want, I can run targeted searches and return direct free-download links (CSV/ZIP/PDF) for datasets and tools; say which format you prefer (CSV, Excel, GitHub repo, or PDFs).
For IT grades 5 to 10, a simple rule applies: Tolerance values increase geometrically with size. Our new charts display this logarithmic progression clearly, helping you spot calculation errors instantly. Input into Calculator:
You are only as good as your data. If your blueprints call out a tolerance you cannot verify, you are gambling with quality. By downloading this new tolerance data using the free link below, you are equipping yourself with the global industry standard for precision.
