Grub screw: Steel, black oxide finish

 |
Grub screws GN 632.1 with ball points
are used with thrust pads GN 631.
The ball diameter d2 is smaller than the thread core diameter,
which allow it to fit over the ball end.
Through the combination of grub screws GN 632.1 and thrust pads
GN 631 with various handles or knobs, simple clamping screws
can be created. |
