The coating for type K or KN (standard spring load) is indicated blue, 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 (GN 615). MVK (Micro encapsulation) is a gluing thread locking (indicated red). see also... • More Information to Thread Lockings → Page 2173 ff.
