Types

  • Type E: without thrust pad

Steel

Tensile strength class 5.8

  • Blackened
  • Thrust point hardened

The thrust point of these screws DIN 6304 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.

Instead of DIN 6311 a thrust pad GN 6311.1 can be used. In that case the tommy screw and the thrust pad have to 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 tp the spit end of the circlip at the lowest possible angle and pressed home.
