A DIN 551 set screw is a headless slotted (screwdriver-drive) grub screw with a flat point that clamps without marring the mating surface; it is the slotted-drive equivalent of the hex-socket DIN 913 and corresponds to ISO 4766. Brassland machines it from free-cutting brass CW617N (CuZn40Pb2) to the standard and to your drawing, as part of our set screws programme.

A straight screwdriver slot (no hex socket); it is the slotted-drive version of the hex-socket DIN 913.

What point does DIN 551 have?

A flat point — it clamps against a surface without biting in, so it does not mar the contact face.

Is DIN 551 the same as ISO 4766?

Yes — DIN 551 corresponds to ISO 4766 (flat-point slotted set screw).

Can DIN 551 be supplied in brass?
