THE ADVANTAGES OF THE SELF¦LOCKING

•Distributes the tensile force along the entire length of the screw thread
•Nominal blocking torque up to 25 % less than that of a conventional assembly
•Completely mechanical, with no chemical additives

THE ADVANTAGES OF THE SCREW

•Screw thread with tolerances tailored to meet requirements, enabling uninterrupted contact between screw and nut
•Fine pitch, increasing the surface in contact with the nut for the same length of thread
•Improved tensile strength thanks to an interior diameter of the profile that is 19 % greater (more than 40 % in section)
•Multiple assembly / disassembly with no change in mechanical properties

The numerous impact resistance tests that have been carried out, clearly show that the threaded assemblies are
totally reliable and now offer a credible response to problems affecting screw resistance.

The tightening torques applied to specimen screws are 25 % less than the values recommended by manufacturers
of chemical “threadlocking” coatings.
