Type E - Without Thrust Pad
Type F - With Thrust Pad DIN 6311
DIN6304 Tommy Screw With Fixed Bar.
These tommy screws have a fixed bar, allowing easy, non slip adjustment of the screw to the desired torque. 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.
An optional foot plate is also available, GN 6311.3
Installation hint for Type F - The thrust pad has to be held at an angle allowing the circlip to drop to the bottom of its groove with the split end downwards. The thrust point is then offered up to the split end of the circlip at the lowest possible angle and pressed home.
Steel ST - Tensile strength class 5.8 (500 N/mm2), blackened.
Thrust point - Hardened.
