A DIN 916 set screw is a headless hexagon-socket grub screw with a cup point — a recessed, sharp-edged ring tip — that bites into a plain shaft to lock a collar, gear or pulley in place, making it the most common general-purpose set screw for permanent location; it corresponds to ISO 4029. Brassland machines it from free-cutting brass CW617N (CuZn40Pb2) — or lead-free CW724R — to the standard and to your drawing, as part of our brass set-screw programme.

Applications

Typical applications for the DIN 916 cup point set screw include permanent location of collars, gears, sprockets and pulleys on a plain shaft, securing fan hubs, couplings and bushings against rotation, holding knobs and dials, and general machine assembly and maintenance. All parts are made to order, so length, point detail, plating and certification are tailored to your specification.

Frequently asked questions

What point does a DIN 916 set screw have?

A cup point — a recessed, sharp-edged ring that bites into a plain shaft for strong, permanent grip; the everyday default set screw.

When should I use a cup point vs a cone point?

Cup (DIN 916) for general permanent location on a plain shaft; cone (DIN 914) for maximum holding into a spotted or drilled seat.

What hex key fits a DIN 916 M6 set screw?

A 3 mm hexagon key; M3=1.5, M4=2, M5=2.5, M8=4, M10=5 mm — shared across DIN 913–916.

Does a DIN 916 cup point damage the shaft?

The sharp ring edge raises a small indent for grip. If the surface must not be marred, use a flat-point DIN 913 instead.
