Beskrivning

Mer information

Fasteners to the given specification have a reduced loadability due to the head geometry according to ISO 898-1. The general change-over from DIN 7991 to ISO 10642 in the practice requires a verification of the application.

Montering

The designation system according to ISO 10683 defines the expected corrosion protection and the friction coefficient range. Further performance specifications of a coating brand used are not specified. Additional thread coating may limit the ability to install zinc flake coated screws < M5 by hand.
