Self drilling anchors are special type of rod anchors. Self-drilling anchor consists of a sacrificial drill bit, hollow steel bar of the appropriate outer and inner diameter and coupling nuts. The anchor body is made of a hollow steel tube with an outer round thread. Steel tube has the sacrificial drill bit at one end and the corresponding nut with a steel end drilling anchor bolts are used in a way that hollow steel bar (rod) has a corresponding sacrificial drill bit on its top instead of a classic drill bit.
Self drilling anchor bolts are an anchoring solution suitable for unstable ground conditions (such as sand, gravel, silt and clay) and soft to moderately cracked rock formations. For projects facing such ground conditions, self-drilling anchors should be regarded as the main productivity solution.
Self Drilling Anchor Bolts include:
A hex nut
A load-bearing board
Extension coupling, if the anchor consists of multiple Anchor rod parts
Hollow anchor
Sacrifice bit
Galvanized anchor
Coupling box
Centralizer
