Also, when there is hard ground, when you can't insert a garden nail with a hook, you can only penetrate it with a hammer or stone with a nail. When driven into the ground, a triangular nail has a better fixing ability than a round traditional nail. In addition, because it is straight, it is often used outdoors as an attachment point for stacking. It is suggested that the four corners of the tent should be fixed with piling, while the width of the door and other places that need to be opened should often be nailed with traditional hook-shaped nails.
