A DIN 546 nut is a low-profile round nut with a screwdriver slot across its face, tightened with a flat-blade screwdriver or slotted-nut driver rather than a spanner; it gives a compact, clean circular fixing. Brassland machines it from free-cutting brass CW614N (CuZn39Pb3) — or lead-free CW724R — to the standard and to your drawing, as part of our brass nut programme.

Frequently asked questions

What tool tightens a DIN 546 slotted round nut?

A flat-blade screwdriver or slotted-nut driver engages the single slot across the nut face — no spanner flats are needed.

Is DIN 546 a cross-hole nut?

No — DIN 546 is the slotted round nut (single screwdriver slot). The cross-hole round nut for a pin spanner is DIN 547, a different part.

Why choose a round slotted nut over a hex nut?

Its compact circular profile fits recessed bores and gives a flush, clean appearance where a hex nut will not fit or is undesirable.

What sizes does DIN 546 cover?

The standard runs from about M3 to M12 for the dimensions shown; larger sizes are available to order.
