The Fischer SX Plus expansion anchor is a specialist for solid materials such as concrete, sand-lime brick, and masonry, thanks to its four-fold expansion. The special fixing wings provide a pre-fixation of the screw, which means it does not need to be held in place during overhead applications. This screw fixation allows the user a flexible and comfortable installation process. Additionally, the flexible anchor rim prevents the anchor from slipping too deep into the drill hole, ensuring secure installation. The high-quality nylon material guarantees a long-lasting secure hold in a variety of solid and hollow building materials.
