Fixed handles, DIN 39 (steel / plastic), Ø16–36: stud thread, pin diameter, length and hex key — dimension sheet
Source: Xem Studio, https://xemstudio.com/objects/fixed-handles-din-39/  (sheet CC BY 4.0)
Basis: Ganter's DIN 39 fixed handle page (five diameters, steel and plastic); numbers only
Catalog version: 2026-10-20

Sizes: see table below
- Ganter's columns in the order printed: d1 (handle diameter), d2 h8 (the plain pin of type D, steel), d3 (the M thread of the stud of type E, steel), the M thread of the plastic version (KT), d4 h13, l1 ≈ (length), l2, l3 and the internal hexagon A/F (hex key). The page prints no units (taken as mm, as for handle diameters 16 to 36) and does not define d4, l2 or l3 in text. A dash means the page shows no plastic (KT) thread for that diameter (16 and 36). The page says the official DIN sheet also lists sizes 10 and 13, which this table does not.
- Shape: the page does not describe the handle in words. Its URL names are 'ballengriffe' (German, ball handles), 'poignées bombées' (French) and 'ogivali' (Italian), and its keywords say 'cylindrical handle'; the sources disagree, so no shape is claimed here. In the Ganter catalogue a U-shaped handle is a separate item (GN 426, see u-handles-gn-426-pull-handles); DIN 39 is not a U-handle.
- No file: the grip profile is not given as numbers. McMaster-Carr sells grip-type handles and knobs with per-part STEP; linked, not copied.
