When assembling screws, there are often problems with starting the thread, resulting in the so-called ‘cross-thread’. This results in damage to or even the destruction of the receiving thread. Loss of production and significant post-processing costs are the result.

Böllhoff Fastening introduced a technical solution . Originally developed for the automotive industry, Navitight can solve the problem efficiently. An undersized thread at the lead of the screw guides the main thread into its correct position, avoiding the dreaded cross thread.

This reliable screwing method has a hexagon flange head and is available in M5 to M14 diameters. Other head styles and diameters are available on request.
