Through bolt anchor Atlantis ETA OPT 1

Pin expanders, also known as expander bolts or concrete expanders, are used for fastening in concrete. The expanders are installed in pre-drilled holes according to the illustrations below. Our pin expanders have a Atlantis finish which gives a smoother finish compared to hot-dip galvanising. This in turn makes it much easier to fit the nut.
