Product Description

IMT Bolt is composed by hollow anchor bar, expansion shell, anchor nut & anchor plate, which is widely used in the medium or hard rock for temporary support and permanent support. It is more safety and efficient through the friction of the open expansion shell & drill hole. This anchor bolt allows for a quick and easy grouting operation, where grout enters through the center hole of the bolt from the bottom and covers it completely. A plastic sealing element is used to seal the drill hole and prevent leakage of grout or resin, ensuring a complete filled hole.
