BS EN 4161 is a European standard on aerospace series that covers crews, pan head, offset cruciform recess, coarse tolerance normal shank, long thread, in alloy steel, cadmium plated.
BS EN 4161 specifies the characteristics of screws, pan head, offset cruciform recess, coarse tolerance normal shank, long thread, in alloy steel, cadmium plated, for aerospace applications.
BS EN 4161 on aerospace series - screws is useful for:
Screws are the most commonly used threaded fastening devices on aircraft. They differ from bolts inasmuch as they are generally made of lower strength materials. They can be installed with a loose fitting thread, and the head shapes are made to engage a screwdriver or wrench.
With the use of BS EN 4161 you get to know the characteristics of screws, pan head, offset cruciform recess, coarse tolerance normal shank, long thread, in alloy steel, cadmium plated which can be very helpful for use in aerospace applications.EN 4161
