Din 7161 Pdf
Because DIN 7161 was the precursor to ISO 2768-1, the values are largely identical. However, modern drawings should utilize ISO 2768-1.
The keyword "DIN 7161 PDF" has specific search intent. Users are not looking for a blog post; they want an immediate, actionable document. They are likely:

DIN 7161 refers to a historically significant German standard that established ISO-deviations and tolerances for holes with nominal sizes ranging from 1 to 500 mm.
Originally published by the German Institute for Standardization (Deutsches Institut für Normung), this document served as a foundational pillar for manufacturing, engineering, and metrology. It ensured high-precision interoperability across machine parts by defining rigid upper and lower deviation limits.
However, if you are searching for a "DIN 7161 PDF" to use in modern engineering, there are critical status updates and standard transitions you need to be aware of. 📉 Status of DIN 7161: Withdrawn and Superseded
If you are looking to purchase or download this document for active engineering projects, keep in mind its active lifecycle has passed:
Official Withdrawal: The standard was officially withdrawn and classified as superseded.
Historical Reference: You can still acquire historical copies for reference or legacy machine maintenance through official standards distributors like DIN Media. 🔄 The Modern Equivalent: DIN ISO 286-2 din 7161 pdf
In an effort to harmonize technical regulations across the global single market, many independent German "DIN" standards were replaced by international ISO equivalents.
The Successor: DIN 7161 was fully replaced by the newer standard DIN ISO 286-2.
What it Covers: DIN ISO 286-2 outlines the tables of standard tolerance classes and limit deviations for holes and shafts.
Why the Change Matters: Using the updated ISO equivalent guarantees that your parts meet globally recognized quality and fitment rules, making it vastly easier to exchange goods and reduce international trade barriers. ⚠️ Beware of Unofficial PDF Downloads
Because technical drawings and legacy contracts still frequently reference old norms, many third-party document-sharing platforms host scanned uploads of the original DIN 7161 sheet.
Precision Risks: Unverified PDFs floating around the web may feature incomplete charts or outdated scanning errors that compromise micro-level tolerance calculations.
Legal and Compliance Gaps: Relying on a withdrawn standard for a new manufacturing pipeline can violate modern quality management system (QMS) frameworks like ISO 9001.
If your project specifies this old standard, it is highly recommended to cross-reference the required tolerances with the tables provided in DIN ISO 286-2 or purchase a legitimate historical copy from an authorized standard store.
DIN 7161 is a historical technical standard titled "ISO Deviations for Holes for Sizes from 1 to 500 mm" (German: ISO-Abmaße für Innenmaße (Bohrungen)). Published in August 1965, it served as a foundational document for the German system of limits and fits, specifically focusing on the internal dimensions of machined parts. Key Technical Details Because DIN 7161 was the precursor to ISO
Purpose: It specifies the permissible deviations (tolerances) for "holes" (internal circular or non-circular features) in engineering and manufacturing. Size Range: Covers nominal dimensions from 1 mm to 500 mm.
ISO Alignment: The standard was based on the ISO recommendation ISO/R 286-1962 but included specific modifications, such as additions and subtractions of certain tolerance fields used in German industry.
Unit of Measure: Deviations are typically provided in micrometers ( ). Current Status and Supersession
DIN 7161 is currently superseded and considered obsolete for new designs. It has been replaced by the more comprehensive international standard DIN ISO 286-2.
Replacement: DIN ISO 286-2 (Geometrical product specifications (GPS) - ISO code system for tolerances on linear sizes - Part 2: Tables of standard tolerance classes and limit deviations for holes and shafts).
Historical Reference: Despite being withdrawn, it is still frequently referenced in older technical drawings, legacy equipment manuals, and when inspecting vintage machinery. Where to Find the PDF
Because the standard is withdrawn, digital copies are primarily found in historical archives or specialized document repositories:
Official Copies: You can purchase historical versions through DIN Media (formerly Beuth Verlag).
Reference Previews: Technical platforms like Scribd host scanned versions of the original 1965 document for informational purposes. As a content creator, addressing this intent means
Understanding DIN 7161: ISO Deviations for Holes DIN 7161 is a historical technical standard titled "ISO-deviations for holes for sizes from 1 to 500 mm". Originally published in August 1965 by the German Institute for Standardization (Deutsches Institut für Normung), it provided essential data for the ISO system of limits and fits specifically for internal dimensions or bores.
While widely recognized in mechanical engineering and precision manufacturing, users searching for a "DIN 7161 PDF" should note that this standard has been largely superseded by modern international standards like ISO 286-2. Core Technical Content
The primary purpose of DIN 7161 was to define the limit deviations (allowances) for hole sizes ranging from 1 mm to 500 mm. These values are typically expressed in micrometers (
m) and are used to determine the maximum and minimum allowable diameters for a part to function correctly within an assembly. DIN7161 | PDF - Scribd
For a ( 40 H7 ) hole:
Thus, the hole must be manufactured between 40.000 mm and 40.025 mm.
DIN 7161 is a German standard that specifies dimensions, tolerances, and technical requirements for metric threaded pins (Gewindestifte) with hexagon socket (internal wrenching) or similar small threaded fasteners used primarily as set screws, locating pins, or for securing components without a head. It defines form factors, thread engagement lengths, permissible deviations, surface treatments, and marking where applicable. The standard ensures interchangeability and reliable mechanical function in assemblies across industries such as machinery, automotive, and tooling.
