ICFS Nut & Bolt Set Wedge Anchor Bolt 8 x 75 mm  (Steel - Pack of 10)

Anchor Fasteners' Wedge Anchor, also known as Sleeve Anchor or Through Bolt Anchor, can be installed through the work piece. This saves considerable time in installation, avoiding alignment errors and providing an exceptionally efficient retention method for fixing to concrete and stone. Its firm fixing action permits repeated removal and replacement of the nut without weakening the anchorage. As the bolt is driven into the fixing hole, the clip is compressed, ensuring a tight interference fit. When torque is then applied to the nut, the tapered section of the bolt retracts through the clip, which expands to create a rapid and permanent grip. As for the internal threaded version TBA-I, it can be installed in normal drill holes without a setting tool.
