It may be wise to weld on a strap around the mast so that the machine screws have shear load instead of an angular load. |
Have a look at the picture once more
The machine screw is
not tapped into the aluminum.
The tang is made in two parts. You make a slot in he mast and thread the two halves in so the flanges sit
inside the mast.
The purpose of the screws is to prevent the tang from falling into the mast.
A neater solution than the mast hounds.
