DIN 926:2003 Slotted Spherical Seat Dog Point Set Screw

DIN 926:2003 Slotted Spherical Seat Dog Point Set Screw combines a slotted drive, a spherical transition, and a dog point, making it suitable for joints where the point enters a locating hole or guide slot while reducing edge stress concentration.

The dog point supports accurate positioning, while the spherical transition provides smoother contact during assembly. This is useful for mechanisms that require repeated adjustment, controlled positioning, or protection of the mating surface. The slotted drive remains easy to operate with standard tools.

It can be used in locating structures, slider stops, transmission adjustments, fixture positioning, and mechanical control mechanisms. Various lengths, materials, and surface treatments can be supplied for wear resistance, corrosion protection, or frequent adjustment requirements.
