An M5 DIN 467 nut is 20 mm across the knurl, with a 10 mm collar and 5 mm overall height, so allow at least 25 mm of finger room.
Common problems
- Slips in the fingers: the knurl is worn.
- Will not seat: the collar is fouling a chamfer.
- Loosens: add a spring washer.
FAQ
What is DIN 467?
The thin knurled thumb nut. It has a knurled head with a small collar and is tightened by hand.
What is the difference from DIN 466?
DIN 466 is the tall version.
Why is M12 not charted?
Only Ganter lists M12, and it says that size is outside the DIN.
Why not M1 to M1.6?
Only one table lists those sizes.
Why no DIN 547 page?
Every free DIN 547 table online is a copy of one source, so there was no independent check. It stays on hold.
