DIN 936 Hexagon Thin Lock Nuts
DIN 936 covers hexagon thin nuts — a low-profile pattern used as a jam nut against a standard nut, or where a full-height nut won't fit. We supply DIN 936 thin nuts in steel across a wide range of metric sizes. Send us your requirement and we'll quote within 24 hours.

Materials & strength
Reduced height
The thin profile takes up roughly half the height of a standard full nut, which suits it to counter-locking and space-limited assemblies.
What is a DIN 936 thin nut?
DIN 936 covers hexagon thin nuts, a reduced-height nut pattern produced in both coarse and fine thread. Thin nuts are typically used as counter nuts or where a full-height nut does not fit.
What is a counter nut and how does it work?
A counter (jam) nut is a second, thinner nut tightened against the main nut so the two bear against each other on the thread. That counter-loading gives the pair strong resistance to rotating loose under vibration.
What is the difference between DIN 936 and DIN 439 thin nuts?
The standards are closely related, although dimensional or technical differences may exist between the two thin-nut patterns at some sizes. If your drawing specifies DIN 439 or DIN 936, send us the requirement and we can identify the appropriate product.
