Product Description
GN615.3 Spring Plunger, with Thread Locking
These spring plungers, GN 615.3, in steel or stainless steel, have a thread locking system as follows:
The PFB patch is a jamming thread locking (Polyamide patch). The coating for type K or KN (standard spring load) is blue, and for type KS or KSN (high spring load) green. For this type of thread locking a relatively high torque is required. Therefore this version with internal hexagon is more preferable than the version with slot GN615.
MVK (Micro encapsulation) is a gluing thread locking (indicated in red). It is available on request and a minimum order quantity applies.
