■Demonstrates reliable strength by installation through torque control and three-sided wedges.
■Demonstrates reliable installation strength with the torque control of the three-sided wedges. Installation can be done by either sides of the anchor as the diameter is the same.
■Overall length can be checked after installation by marking on the head.
- Drill vertically to target surface with the determined preparation diameter and preparation hole depth.
- Use a dust collector or blower to thoroughly remove chips in the hole.
- Insert a big one.
- Hammer in until the washer contacts the installed object.
- Use a torque wrench to tighten the nut to the specified torque value.
- The three-sided wedge expands and installation is completed.
- Wear safety protection equipment such as protective glasses, a helmet etc., during installation.
- Use a dust collector or blower to thoroughly remove chips in the hole.
- Select overall length of anchor in consideration of thickness of installed object.
- Align the end face of the nut with the end of the tape to set.
- For installation, use a torque wrench to tighten to the specified torque.
