GN 418.2 Steel Cam Point Screws

Product description


Cam point screws GN 418.2 are simple clamping elements for a wide variety of different uses. They are sturdy and compact, requiring a minimum of installation space and offering ultimate convenience and ease in handling.

The F clamping forces given in the table refer to the maximum permitted tightening torque and the specified screw-in depth = t as shown on the “Assembly Instructions”.



  • Case hardened HRC 56 ±1
  • Property strength class 8.8
  • Zinc plated, blue passivated finish

Sketch GN 418.2 function

The head of the cam point screw has two cams: a radial clamping cam (with additional 30° taper) and an axial draw-down cam.

The cam ensures that the clamping force is the same in any angular position. The cam is also

Force components act on the clamping point which generates a draw-down effect and, in addition to the friction, cause the workpiece to be pressed up against a fixed stop. An additional draw-down effect is created by the thread and the 30° taper.

Assembly Instructions

Sketch GN 418.2 Assembly

•Position the threaded hole/s as specified.

•Screw the cam point screw in to the desired height and place it with its flat side facing the workpiece (note the minimum screw-in depth t)

•For clamping effect above the head taper, the minimum clamping height should be h2

•A turn of approx. 135° is required for clamping
