Frequently asked questions

What tool tightens a DIN 1816 nut?

A pin spanner (hook-pin type) that engages the radial holes drilled into the nut's cylindrical edge.

What is the difference between DIN 1816 and DIN 1804?

Both are fine-thread shaft nuts operated from the side: DIN 1816 has radial holes in the edge for a pin spanner; DIN 1804 has slots in the edge for a hook (C-) spanner.

Can DIN 1816 be supplied in brass?

Yes — turned to order in CW614N brass; stock catalogue parts are usually steel or stainless.

What thread does DIN 1816 use?

Metric fine pitch, from M6×0.75 upward. See the datasheet for the dimensions per size.
