Like expansion anchors, rear expansion anchors are widely used for installation and fastening in concrete structures, but rear expansion anchors are more cumbersome in terms of installation efficiency than expansion anchors. During installation, it is necessary to expand the pre-drilled hole with a specific rear expanding drill bit to carry out the subsequent installation and tightening.



Eight steps are required for the installation of the rear reaming anchor bolt: drilling-cleaning dust-inserting the reaming drill bit-adjusting the diameter of the reaming hole-reaming-inserting the anchor bolt-percussion installation-tightening

The installation process is cumbersome. If you encounter a large-scale project installation, the entire installation time will be stretched for a long time, which will seriously affect the construction period of the entire project.

The installation of concrete self-tapping anchors can be said to be quite convenient and efficient.


Only drilling-cleaning-installation-locking can be completed in four simple steps, greatly shortening the construction period.
