Set screw with hexagon socket and dog point DIN 915 / ISO 4028, M 8x40, steel 45 H

The set screw with dog point secures a hub, a shaft collar or a lever on the shaft and transmits the torque through the dog point at its end. In addition the sheet lists a length of 40 mm. Decisive for the selection is a hexagon socket of 4 mm.

Benefits

• Thread M 8 at a length of 40 mm, so the screw sits fully inside the thread and does not stand out beyond the hub.
• Hexagon socket 4 mm, so the screw can be tightened recessed and with a repeatable torque.
• The dog point engages in a hole or groove in the shaft and secures the hub against turning by form fit.
• Made of steel 45 H to DIN 915.

Applications

On a shaft collar the M 8x40 set screw keeps the hub in place without standing out beyond the contour.

Standards and conformity

The 4 mm hexagon socket follows the standard, so no special tool is needed.
