Brass Nuts to DIN / ISO · Jamnagar, India
Hexagon domed cap (acorn) nut, high form — machined in brass CW614N to standard and to your drawing.
Home / Products / Standard Parts / Brass Nuts / DIN 1587
A DIN 1587 nut is a high-form hexagon domed cap (acorn) nut with a closed dome that fully covers the bolt thread end for a clean, finished and protective appearance; it is the tall counterpart to the low DIN 917 cap 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.

Dome height. DIN 1587 is the tall (high) acorn cap; DIN 917 is the low / shallow cap nut. Both have a closed, blind end.
Yes — it has a closed dome (blind thread) that fully encloses and protects the projecting bolt end.
No. It is protective and decorative, not a locking device.
Brass offers corrosion resistance and a premium decorative finish, and takes nickel or chrome plating well for visible fittings.
