For the connection where the head of the slotted nut is slightly higher or flat than the plane of the fixed part, a hexagonal nut with a slightly smaller outer diameter than the head of the slotted nut can be used and placed on the head of the hexagonal slotted nut, and then the nut and the hexagon Slotted nut heads are spot welded together. After cooling, use a movable hand to twist the nut to take out the hexagon socket bolt.
