The ETA Approved Ankerbolt Socket Bolt is a self tapping anchor for use in a variety of base materials. The undercutting action provides a positive anchorage with no expansion forces.
The Dual Thread allows for the use of M8 or M10 thread rod with the need for only one socket.
The choice of M8 and M10 gives options for the diameter of threaded rod being used.
