DIN 547 Brass Two-Hole Round Nut

Round nut with two face holes (two-pin spanner) — turned in brass to standard and to your drawing.

Home / Products / Standard Parts / Brass Nuts / DIN 547

A DIN 547 nut is a round nut with two holes drilled into one face, turned for a two-pin (face) spanner; it gives a compact, flush fixing on shafts and spindles where a hexagon nut will not fit, and is commonly machined in brass. Brassland machines it from free-cutting brass CW614N (CuZn39Pb3) to the standard and to your drawing, as part of our brass nuts programme.
