The Self-Cutting Mechanical Anchor by TEDUN is a high-performance fastening solution engineered for secure anchoring in concrete substrates. Composed of a precision-machined threaded rod, thrust sleeve, flat washer, spring washer, and nut, its core innovation lies in integrated carbide-tipped cutter blades at the leading end. During installation, these blades automatically carve an inverted-cone interlock cavity into the concrete borehole wall—eliminating the need for specialized undercutting tools. A synchronized mechanism drives efficiency: tightening the nut activates the thrust sleeve to trigger both cutting action and key deployment, creating an immediate mechanical interlock between expansion keys and the concrete cavity. This anchor excels in C25-C80 concrete, delivering consistent tensile resistance (≥70kN@M16) while reducing installation steps by 50% (≤1 minute per hole), making it ideal for time-critical projects.
