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 for secure mounting. The included screws are optimally matched to the Fischer SX Plus expansion anchor. The high-quality nylon material guarantees a permanently secure hold in a variety of solid and hollow building materials.
