- The anchor features a hole for passing wires, etc., through the tapered bolt section, which means fewer components are needed as it does not require the use of eye bolts, eye nuts, or hanging hardware. This is expected to reduce costs for safety measures, improve workability, and shorten construction periods. - Its simple structure eliminates the need to check for screw loosening during inspections after construction, which is expected to enhance the reliability and efficiency of inspections. - It is a post-installed metal anchor that uses a sleeve-driven method. With a male thread design, when tensile force is applied, the sleeve expands in response, providing a more reliable crimping effect. It has been designated as a recommended material by the Japan Seismic Ceiling Construction Cooperative.

When the cap set on the nut reaches the appropriate torque, the inner claws break, and the cap spins freely to indicate that the installation is complete. A capped state indicates that installation is not yet complete. The work is finished when the cap is removed and the nut is exposed. This prevents not only forgetting to tighten or insufficient tightening but also seizing due to over-tightening. It is possible to tighten with the appropriate torque using only an impact wrench, without the need for a torque wrench or special tightening machinery.

The "Padem Sheet" adsorbs harmful substances (heavy metals) in the soil generated during tunnel excavation and construction work, preventing their outflow.
