It covers hole tolerances (Bohrungen) for nominal dimensions ranging from 1 mm up to 500 mm.
: Includes common "fit" classifications (e.g., H7, H8, H11) that determine how a shaft and hole will interact (e.g., clearance, transition, or interference fits). Where to Find High-Quality Documentation
Official Beuth or DIN Media PDFs have a subtle "DIN Media" watermark or metadata. Extra quality usually implies a digital-born PDF (from a CAD plugin export) or a professionally descreened scan.
: Companies like REYHER often include historical DIN tolerance tables in their comprehensive "Technical Information" guides for fasteners and machining. Comparison of Hole Tolerances (Sample from DIN 7161) din 7161 pdf extra quality
DIN 7161, officially titled "ISO-Abmaße für Innenmaße (Bohrungen), für Nennmaße von 1 bis 500 mm" (ISO deviations for internal dimensions (holes), for nominal dimensions from 1 to 500 mm), was a foundational standard published in August 1965. Published by the German Institute for Standardisation (Deutsches Institut für Normung), it was a direct application of the early ISO system of limits and fits.
: Range from A to ZC. "H" represents a tolerance zone where the minimum limit equals the nominal size.
“Extra Quality” in the context of DIN 7161 implies purchaser-defined, tighter geometric and surface requirements beyond standard grades, demanding controlled manufacturing, metrology, and documentation. For reliable procurement and manufacture, specify numeric limits, measurement methods, and acceptance criteria rather than relying on the qualitative label.

Understanding DIN 7161: The Blueprint for ISO Metric Fits and Tolerances
If you are searching for a reference, you likely need high-clarity tolerance tables for mechanical design, quality control, or legacy system maintenance. This comprehensive guide breaks down the structure of DIN 7161, its technical applications, and how it translates to modern ISO standards. What is DIN 7161?
