and stainless steel. A problem that usually results in the machine screw corrosion
welding to aluminum. Not to mention the huge increase in strength of a ss "rivet nut" versus an aluminum one with aluminum threads.
- - If such an animal - ss "rivet nuts" are not available then the discussion is moot as you can only use what you can get.
- - Strength is a major problem with stainless steel screwed into aluminum. Which is why I prefer to use aluminum pop rivets whenever possible. They fill the hole and expand out behind the mast wall. To remove the item I just use a drill bit to remove the head
of the rivet and slide the item off the mast.
- - This might be where mounting an aluminum or stainless steel bracket onto the mast with rivets and then attaching the line clutch with ss machine screws and nuts might be a better solution especially if the mast is not very large.
