Spring bolt with lock nut

The plunger pin of the spring bolts GN 313 does not protrude in the inoperative position. It can be operated manually or in Type D and DK mechanically (pneumatic cylinder, cam plate, etc.) when it will protrude only as long as it is operated. Using the internal thread at identification 2 on the pressure side, special pressure bolts or a rod arrangement can be operated, for instance. The screw drivers GN 613.1 (available as accessory) shorten the assembly time and make it easier to hold the mechanism in place while fixing the lock nut. The screw driver is inserted in the side between the knob and guide, where it engages the slot in the guide.
