Information

Grub screw: Steel, black oxide finish

GN 632.1 grub screws are typically used with GN 631 thrust pads, making a low cost solution for clamping operations or for load bearing purposes.
A good feature of these components is a smaller size ball diameter than the trunk of the threaded stud. As a result, the studs can be screwed into position from the ball side. The thrust pad can easily be hammered onto the ball end of the screw, and also easily dismantled.
Tensile strength 500 N/mm2
