Ball: Steel, hardened, plain finish

GN 615.3 ball plungers are used as detents, and for push-on and push-off applications.
Snap-indexing mechanism applications, together with various control levers, are of particular interest.
The hexagon socket end makes these plungers slightly longer than the GN 615 spring plunger with slot. In other aspects they are identical.
Stainless steel ball plungers, threaded body type, see GN 615.
PFB patch for sizes M20 - M24 available upon request in certain minimum quantities.
MVK microencapsulation precote patch available upon request in certain minimum quantities.

See our technical section for securing
