This pack comes with all the nuts, bolts and washers needed to complete a wall-seam for an Asahi pool. Some older Asahi models use a washer-bar that did not need individual washers. If you have this type of pool, this hardware pack will not work for you. Please look at the picture to compare to your pools seam. If your pool uses a service panel, you will need two hardware packs because your pool has two seams. If your pool only has a single seam, then one pack is all you need. This does not include any other hardware for your pool. It is only the hardware to bolt the seam of the pool wall together.
