Assembly notice
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.
Warnings
Set screws are not intended to be tensile-loaded.
