SHERPA locking screws type L series 5x47.8/20

TORX (from the English word ‘torque’) is the registered word mark for a screw drive profile, the standard designation for which is ‘internal six-lobe’ (English: ‘six lobe, internal socket’). With the six-lobe internal socket, the screw and tool are subjected to less radial stress than with the traditional internal hexagon, and consequently suffer less damage. Torque is transmitted more directly via the radial parts of the tooth flanks rather than via the faces of the hexagon.

During galvanizing (named after Luigi Galvani) or electrolytic galvanizing, the steel is immersed in a zinc bath. It is an electrolyte bath in which direct current flows. The current flow ensures that the metal ions in the steel (iron and zinc) attach to the surface of the steel parts. The zinc layer created by galvanizing is particularly thin - depending on the material thickness of the galvanized part, approx. 3 - 10 my.
