Screw-locking devices

　　made of polyamide 6

　　for hexagon head screws and round head screws as 

　　well as for cheese-head screws with hexagon sockets.

　　The DUBOSCHWEITZER

　　®

　　screw locking devices are 

　　the ideal way to lock, seal and insulate your screwtype connections.

　　A tried and tested concept that has been used for 

　　more than 55 years in many industrial sectors!

　　Multiple forms of locking and sealing, because screwlocking devices

　　•  can be pressed into the threads of the screw bolt 

　　and the nut,

　　•  provide especially active frictional locking with the 

　　bolt and therefore prevent the locking ring from 

　　rotating around the bolt,

　　•  place themselves around the hexagon of the nut 

　　and therefore prevent the nut form becoming 

　　undone on its own,

　　•  help prevent any leakage losses by filling in all dead

　　spaces

　　Noise absorption and durability,

　　because screw-locking devices

　　•  absorb the vibrations occuring in the screw 

　　connection

　　•  posses plastic-elastic behaviour,

　　•  do not age or wear out and can therefore always be 

　　used again without affecting any of the above-mentioned advantages.

　　Insulation and material surface protection, because 

　　screw-locking devices

　　•  are chemically resistant to alkaline liquids, solutions

　　of inorganic neutral salts, oils, fats, benzenes, benzol, alcohol, acetone, diluted acids, and seawater,

　　prevent electrolytic corrosion between the joined

　　•  parts and bolt material fatigue.
