DIN 6334 - Hexagon coupling nuts

Paid access

Hexagon coupling nuts, also called connector or extension nuts, three times as tall as the thread diameter (height = 3d). Used to join two externally threaded parts, typically threaded rods, end to end. The hexagon is the same as a DIN 934 nut of the same size, sharing its width across flats; only the height differs. Covers metric coarse pitch from M6 to M36. Both ends are chamfered. There is no ISO replacement.
