Product Description
GN918.2 Clamping Bolt, Downward Clamping
These clamping bolts, GN 918.2, are fitted with a rotating helix. They allow rapid and safe clamping and releasing with a relatively long movement and high clamping force. The small rising angle of the helix makes it self arresting.
The ball handle is linked with the clamping mechanism via a serrated ratchet thus allowing an individual positioning of the hand lever.
Clamping bolts offer the advantage that they can be rotated away from the clamping area after release.
Clamping bolts can also be used as stepless adjustable end stops. If the washer is removed the bolt can be clamped direct to its support.
Ball point screws GN605 with flattened ball are recommended for use with these clamping bolts.
