Seritë e hapësirës ajrore - Vidha, me kokë të lugët, fole me gjashtë ndarje, trup normal me tolerance të madhe, me gjatësi mesatare filetimi, prej lidhje çeliku, veshur me cadmium - Klasifikimi: 1100 MPa (në temperaturë mjedisi) / 235 °C

Aerospace series - Screws, pan head, hexalobular recess, coarse tolerance shank, medium length thread, in alloy steel, cadmium plated - Classification: 1 100 MPa (at ambient temperature) / 235 °C

Scope

This European Standard specifies the characteristics of screws, pan head, six lobe recess, coarse tolerance shank, medium length thread, in alloy steel, cadmium plated.
Classification: 1 100 Mpa 1) / 235 °C 2).
---------------
1) Minimum tensile strength of the material at ambient temperature.
2) Maximum temperature that the screw can withstand without continuous change in its original characteristics, after return to ambient temperature. The maximum temperature is determined by the surface treatment.
