Nycote® – the insulating coating … Where thick deposits impair the easy running properties of screws, Nycote offers the ideal protection: from galvanic deposits, as well as cataphoretic primers and paints applied during electrodeposition, particularly when using the cathodic principle. The Nylok Fasteners Corporation in the USA, Licensor to KerbKonus, developed this special coating process. A special powder blend – based on Teflon – is applied by means of heat to the screws as a closed layer which completely covers the thread. As a consequence, protective layers and primers applied during the electrodepostion process do not adhere to the threads, and so do not impair subsequent installation. In the case of parts coated with Nycote, the coefficient of friction is reduced when tightening the screws. This characteristic makes it easier for the prescribed installation conditions to be complied with. 18 The solution: Nycote® Fields of application Exhaustive testing has shown that Nycote has characteristics which prevent cataphoretic primers or paints from adhering to threads. Wherever electrodeposition or galvanic treatments are used and threaded areas have to be covered over, it makes sense to use parts pre-coated with Nycote. Wherever the Nycote protective layer covers the thread, it is not possible for primers or paints to adhere to the surface. Threaded components – both internal and external threads – are pre-coated using a special technique. They then go on to be processed in the accustomed way without problems on the production line, for example using welding machines. Another benefit: This processing method also prevents the often troublesome adhesion of welding beads. When using this method, the application of Nycote on the coupling elements serves to cover the required threaded area: This effectively prevents paint deposits on the threads which would impair installation. Another benefit of Nycote: Improved screw sliding properties. Nycote reduces the coefficient of friction during installation and guarantees a defined clamping force. The process is ideally suited for the fast installation processes demanded by many branches of industry today. Nycote replaces the coats of wax or lubricant which are often applied to improve sliding properties.

... technologies for a reliable hold Benefits of applying an insulating coat … How the Nycote coating works The benefits at a glance Nycote is a patent-protected coating method involving the application of insulating (non-conductive) Teflon powder on a heated threaded component. This forms a protective layer against unwanted deposits of primers, paints and other surfaces during electrodeposition. • Nycote reduces the coefficient of friction, so allowing weld nuts and bolts to be more quickly installed and eliminating the need for subsequent oiling or greasing. The Nycote thread coating is the...

As in most cases a torque-controlled method of screw connection tighte- ning is used, the required pretension force FV is determined by the tighte- This means that the pretension force FV cannot be measured directly. It is calculated indirectly as a function of To simplify, a minimum pretension force FV min. is required...
