GN 817.4 Indexing Plungers with T-Handle

Today we're introducing you to our series GN 817.4 Steel or Stainless Steel Indexing Plungers with T-Handle, with and without Rest Position, available in metric sizes.

Steel Version
These RoHS-compliant plungers are similar in design to GN 817, but have a T-handle instead of a round knob. This shape is advantageous when greater unlocking forces occur. It also allows better visual orientation of the indexing position of the Type C version (version with rest position). Type C GN 817.4 indexing plungers are used in applications where the plunger must not protrude continually. In that case the knob is retracted and afterwards turned by 90°. A notch keeps the plunger in this position.

Stainless Steel Version
In the steel version, body and plunger pin are steel with black oxide finish. In the stainless steel version, body and plunger pin are European Standard No. 1.4305 stainless steel (American Standard Series 303), with the plunger pin also chemically nickel-plated. The T-handle is technopolymer plastic (Polyamid PA), and is not removable. Lock nut is steel or stainless steel, ISO 8675 (DIN 439).
