These nuts feature a standard M4 thread diameter with a 0.7 millimeter thread pitch, a 10 millimeter flange diameter, a 7 millimeter width across flats, and a total height of 4.5 millimeters.
Can these stainless steel nuts be used outdoors?
Yes, they are made from 304 stainless steel, which provides excellent resistance to rust and corrosion, making them suitable for both indoor and standard outdoor environments.
