Fischer Japan (Tokyo, President Hirofumi Arai) has commenced sales of the Strong Undercut Anchor "FSU" designed exclusively for heavy objects in Japan, starting from October last year.

This marks the debut of the first self-drilling expansive anchor of the Fischer brand in Germany, featuring six robust blades that drill and expand the hole on their own. The plastic wings grip within the hole, making it suitable for upward construction as well. In comparison to the conventional expansive anchor FZA, the FSU boasts approximately twice the tensile strength and three times the shear strength. The DMC code imprinted on the anchor allows easy product information verification on-site through scanning with a device.

The straight hole is drilled using a dedicated bit, and construction is carried out with a specialized setting tool. Removal of the sleeve part is possible with a dedicated removal tool. Ideal for infrastructure projects such as power plants, fuel tanks, bridges, railways, and tunnels, the FSU is expected to be adopted in the growing market for infrastructure maintenance due to its removable feature. Its minimal impact on the base material makes it suitable for construction in places with constant micro-vibrations.

President Arai expressed his satisfaction with the product release, stating, "We are excited to introduce a new product that users have eagerly awaited, a self-drilling type in the expansive anchor market, which Fischer pioneered globally. The importance of anchors has increased, as seen in incidents like the Sasago Tunnel accident. We are delighted to meet these needs with our new product."

Fischer Japan aims to contribute to society by providing high-performance, reliable, and safe fastening products from Fischer Germany in the construction market, addressing challenges such as infrastructure and structural aging, and labor shortages.
