Thanks to its 4-way expansion, the fischer SX Plus expansion plug is the specialist for solid building materials such as concrete, sand-lime brick and masonry. The special fixing blades ensure pre-fixation of the screw, which means that it does not have to be additionally held in place for overhead applications. This screw fixation allows the user a flexible and comfortable setting process. The flexibel plug edge also prevents the plug from slipping deeper into the drill hole for secure installation. The high-quality nylon material guarantees a permanently secure hold in a wide range of solid and perforated building materials. *4-way expansion for high load values.*Fixing blades for screw fixation and flexible mounting.*Installation of the plug possible with little effort.*Plug edge prevents slipping deeper into the drill hole.*Noticeable tightening torque prevents overtightening of the screw.
