Serie der Muttern
Hex, square, flange, nylon-insert, lock and rivet nuts in metric coarse and fine thread. Manufactured to Class 8 and Class 10 strength grades with zinc plated, hot-dip galvanized or plain finishes.
Sechskantmuttern
Standard hexagon nuts in metric coarse and fine thread, produced to Class 8 and Class 10 strength grades. Used with hex head bolts and studs throughout general engineering and structural assemblies.
Vierkantmuttern
Square nuts with a wider bearing face than hex nuts and four flat sides for a wrench. Preferred in timber connections, channel and bracket assemblies where the nut must not rotate.
Flanschmuttern
Flange nuts with an integrated flange that spreads the clamping load and removes the need for a separate washer. Serrated flange versions resist loosening in vibrating assemblies.
Nylonmuttern
Nylon-insert lock nuts with a captive nylon collar that grips the bolt thread and resists vibration loosening. Effective across a wide temperature range and reusable for a limited number of cycles.
Sicherungsmuttern
Prevailing torque lock nuts that hold their position under vibration. All-metal types need no nylon insert and suit higher-temperature applications; nylon-collar versions are also available.
Nietmuttern
Rivet nuts (blind threaded inserts) that create a permanent load-bearing thread in thin sheet metal from one side only. Available in steel, stainless steel and aluminium, with knurled or plain bodies.
