Self drilling anchor is a kind of tool commonly used in engineering anchorage support. It enhances the anchorage of surrounding rock layers and soil layers through drilling, grouting and anchoring, and enhances the stability of the project and the longevity of the building. Due to its wide application and strong adaptability, it has applications in tunnel advance support, slope protection, hydroelectric engineering, deep foundation pit construction and other projects. The self drilling anchor bar is a precision-machined combination anchor-drill of high-grade steel, specially tempered to insure clean, close-fitting holes and plated to resist rust and corrosion. At the surface end of the self drilling anchor are internal threads, precision-machined to receive standard machine bolts or machine screws. The design of the whole thread can freely cut or extend the length of the anchor bolt, and the construction site area is no longer limited. Self drilling anchors are permanently secured after expansion though fixtures may be readily removed and replaced. Self drilling bolts are the main products of Sinorock®. As a self drilling anchor manufacturer and developer, self drilling anchor bolts produced by Sinorock® have been widely used in many projects, and the quality of products has been recognized by users.
