Tension bolt

Clamping bolts GN 918.7 have a circumferential wedge surface. They allow for rapid and secure clamping and releasing with a relatively large clamping range and with high clamping force. Owing to the small pitch angle (wedge angle), the clamping bolt is self-locking. Fastening via screw from the operator‘s side bridges a greater clamping range. A sufficiently large screw-in depth t is necessary to safely absorb the screw forces. The ball levers of types KVS / GVS form a positive connection with the eccentric cam by means of a serration. During assembly, the lever can thus be fixed in a position favorable for clamping or, in the relaxed position, rotated out of the clamping range.
