General information
Features and applications
GN 709.8 grub screws are suitable for clamping of parts to be machined. The flat-faced (non-reversible) ball allows to compensate for any misalignment of the contact surfaces up to 10°.
The O-ring keeps the ball in position and prevents the penetration of dirt.
