DIN6306 Tommy Screw With Movable Bar.
These tommy screws, DIN 6306, allow easy adjustment of the screw to the desired torque. The movable bar is held in any position by the pressure spring.
The end caps are pressed on to the bar and thus limit the bar travel, they can also be supplied separately should the bar be plated first. The official DIN standard sheets provides for steel rings at this point.
The thrust point of these screws is designed to be used with or without a thrust pad for clamping. The snap ring is a simple and quick method to connect the thrust pad to the tommy screw.
