Insulate the bolt connection

KORREX® nut caps with KORREX® insulation bushes and Dubo® retaining washers completely insulate the bolt connection.

Sealing and protection

Pressing the nut cap onto the nut turns a hexagonal nut into a cap nut. The original connection of the nut remains intact, while the thread is sealed and the nut and bolt are protected against corrosion and other negative effects. This both improves the security of the construction and gives a more attractive finish.
