The
through bolt anchor TBA can be installed through the work piece. This saves
considerable time in installation avoiding alignment errors and provides 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. |
