Self Drilling Anchor Bolt By Re Bar Couplers India Private Limited

The self-drilling hollow bar anchor system consists of a hollow threaded bar with an attached drill bit, enabling drilling, anchoring, and grouting in a single operation. The hollow bar allows air and water to pass through during drilling, removing debris and facilitating immediate grout injection. Grout fills the hollow bar, covering the entire bolt. Couplers can extend the bolt length, while nuts and plates provide tension.

JB Engineering offers self-drilling anchors in R25, R32, R38, R51, and T76 variants, along with accessories such as anchor nuts, anchor plates, anchor couplers, and drilling bits tailored to the geological conditions of the project site (Type EX, EXX, ES, ESS, EY, EYY).
