butterfly anchors

The design of an M8 wedge anchor is simple yet effective. It consists of a threaded rod with a nut and washer, accompanied by a wedge-shaped expansion sleeve. When installed, the anchor is drilled into a pre-drilled hole in the concrete, and then the bolt is inserted and tightened. As the bolt is tightened, it pulls the wedge-shaped sleeve against the sides of the hole, creating friction and causing the sleeve to expand. This expansion locks the anchor securely in place, providing a strong hold that can withstand significant loads.

  • The designation 5 8 might initially seem cryptic, but it refers to specific measurements and material characteristics that are engineered to meet particular performance requirements in hydraulic systems. Typically, hydraulic hoses are encoded in a manner that informs the user about their inner diameter, working pressure, and spiral wire reinforcement.
