Din 76a Pdf =link= Jun 2026
Form B is a shortened external thread undercut intended for situations where space is severely constrained. Its defining dimension is (i.e., shorter than Form A).
) slightly lowers the tensile strength of the bolt at that specific cross-section.
Most modern 3D modeling software packages (like SolidWorks, Autodesk Inventor, or Fusion 360) have built-in hole and thread features that can automatically generate DIN 76 thread undercuts based on the selected thread size. Conclusion and Download Guidelines
While Leo usually uses (the standard "long" version), the DIN 76-1 standard offers others for different scenarios:
) will have a much wider and deeper undercut than an M12 fine thread (
When designing or manufacturing threaded fasteners, ensuring a proper fit against a mating surface is critical. One of the most vital standards for achieving this is , specifically Form A (DIN 76A) . This standard governs the dimensions of thread undercuts for components with external metric threads.
During the manufacturing of external threads—whether via chasing, rolling, or milling—the threading tool cannot cut a full, perfect thread profile all the way to a perpendicular shoulder. It naturally leaves a partial, non-functional thread form known as a thread run-out.
: Used for external threads (bolts, screws, and studs). Design Type : Known as "Normal Design" (longer than Form B). Core Dimensions : Width ( ) : Typically approximately (where is the thread pitch). Diameter (
When programming a CNC lathe to execute a DIN 76A undercut, keep the following best practices in mind:
