Spring elements GN 513 are universal pressure elements used as detents, positioners or for clamping with spring pressure. The spring loaded nose can be used for a push-on or push-off operation. In addition the spring loaded nose cannot rotate. At the pulling end the female thread will accept a pulling rod or an operating knob. The version with a female thread at the pushing end (Type I) can be fitted with a special plunger nose. The spring element can be screwed into a thread at the hexagon on the pulling end or the spanner flats at the pushing end of the plunger.
