Hex Bolt Manufacturers introduces the function and disassembly method of hexagon bolts:
The function of the hexagonal bolt is to fix the front axle and the rear axle by fastening screws passing through the front axle and the rear axle, thereby fixing the frame and the tires together. To prevent the nut from loosening, a split pin must pass through the slot of the slotted nut to fix the nut, and the split pin must pass through the middle of the shaft screw to fix the slotted nut.
How to remove the hexagonal bolt: For the connection where the head of the hexagonal slotted nut is slightly higher or flat than the plane of the fixing member, the hexagonal nut with the outer diameter slightly smaller than the head of the hexagonal slotted nut can be placed on the head of the hexagonal slotted nut, and then Spot weld the nut to the head of the hexagonal slotted nut. After cooling, you can tighten the nut with a movable ha
nd and take out the hexagon socket bolt.
