The Fischer SX Plus expansion anchor is a specialist for solid materials such as concrete, sand-lime brick, and masonry, thanks to its four-way expansion. The special fixing wings ensure a pre-fixation of the screw, which means it does not need to be held additionally during overhead applications. This screw fixation allows the user a flexible and comfortable installation process. The flexible anchor rim also prevents the anchor from slipping too deep into the drill hole, ensuring secure mounting. The high-quality nylon material guarantees a permanently secure hold in a variety of solid and hollow building materials. This variant with a greater anchoring depth is ideal for fixings in hollow building materials, aerated concrete, and for plaster coverage.
