A DIN 917 nut is a low-form hexagon cap (dome) nut with a closed end that covers the bolt thread in a compact, shallow profile; it is the low counterpart to the high DIN 1587 acorn nut. 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.

Dimensions in mm to DIN 917. Widths across flats follow the current ISO series (M10/M12/M14 = 16/18/21 mm; older DIN editions used 17/19/22 mm). The shallow dome blends into the hex, so there is no separate dome diameter. Sizes and tolerances are made to your drawing on request.

Applications

Typical applications for the Brass Cap Nut (Low Form) include low-clearance capped bolt ends, appliance and white-goods trim, sanitary fittings with short threads, and light decorative hardware. As all parts are made to order, sizes, threads, plating and certification are tailored to your specification.

Frequently asked questions

What is the difference between DIN 917 and DIN 1587?

DIN 917 is the low / shallow cap nut; DIN 1587 is the tall acorn cap. Use DIN 917 where height is limited or the thread projection is short.

Does a DIN 917 cap nut lock the joint?

No — like all cap nuts it is protective and decorative, closing off the bolt end rather than locking it.

Is DIN 917 a blind nut?

Yes — it has a closed (blind) end, so the thread does not pass through.

When should I use a low DIN 917 instead of a high DIN 1587?

When installation height is restricted or only a short length of thread projects past the nut.
