Frequently asked questions

What tool tightens a DIN 1804 nut?

A hook (C-) spanner that engages the slots in the nut's outer edge.

What thread does DIN 1804 use?

Metric fine pitch — e.g. M20×1.5. The standard runs from M6×0.75 up to M200×3.

Can a DIN 1804 nut be made in brass?

Yes — turned to order in free-cutting brass CW614N; catalogue stock is usually steel or stainless, but brass suits non-magnetic and corrosion-sensitive uses.

What is the difference between DIN 1804 and DIN 1816?

Both are round nuts; DIN 1804 has slots in its edge for a hook spanner, while DIN 1816 has radial holes in its edge for a pin spanner.
