I used it for flap repair of a noodle boiler. Originally all-aluminum rivets were used so purchase here. It was uneasy because there was no response when caulking for all aluminum, but it seems that it has been caulked properly.
This place is safe for the same material of the shaft and the shade so as to avoid electric corrosion in places that are easily exposed. However, I did not have the size I want, so I want you to increase the variation of the size.
