Types

  • Type E: Without thrust pad
  • Type F: With thrust pad DIN 6311

Tommy screw

Steel

  • Property class 5.8
  • Blackened
  • Thrust point hardened

Thrust pad for type F

Steel

  • Case-hardened
  • Blackened
  • Snap ring
  • Spring steel wire

The thrust point of these screws DIN 6304 is designed to be used with or without a thrust pad for clamping. Installation of the thrust pad is made easier if the pivot is positioned at an angle against the closed side of the snap ring and then pressed in.

In place of DIN 6311 (type E), it is also possible to use a thrust pad GN 6311.1 or a foot plate GN 6311.3. In this case, the tommy screw and thrust pad or foot plate must be ordered separately.

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.
