Self Drilling Anchor Screw

Our firm is supplying a wide range of Self Drilling Anchor Screw to our patrons. Sinorock Self drilling anchors consist of a fully threaded hollow bar,which serves as drill body with couplers and a drill bit suited to different types of ground conditions.They are recommended in cases where a cased hole is necessary.
Self-drilling Anchors are successfully used for anchoring in poor ground, cohesive and non-cohesive soils, and in the case of unstable boreholes.
The main advantage of self-drilling anchors is their high efficiency, as several operations can be performed at once: drilling, installation of the anchor and sealing/grouting.
