GN918.1 Clamping Bolt, Upward Clamping.
These clamping bolts 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.
Bolt and washer are matched to allow an effortless release from the clamped position. The washer "saves" special requirements to the execution of the female thread and the clamping bolt can therefore also be
used on T-Nuts on machine beds.
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 are recommended for use with these clamping bolts.
Clamping bolt and washer, case hardened.
