· If you are using it for plating and require surface treatment, we recommend applying GEOMET coating.
· We use MJ (Aerospace) screws, and there are no issues with regular NUTs for fastening.
· For strength grades 15.9 and 16.9, it is available for custom production on order.
* Please scroll horizontally to view.
· In aerospace specifications, MJ screws have larger root radii compared to standard screws, which helps to alleviate the notch effect and increase resistance to fatigue.
