Thanks to its 4-way expansion, the fischer SX plug optimally transfers forces in solid and perforated substrates, such as concrete and masonry. The plug's practical anti-rotation lugs allow the screw to be inserted without needing to be tightened, leaving your hands free. The thin collar prevents the plug from being pushed further into the drill hole during installation, but it can still be easily pushed through the attachment part. The fischer SX Plus plug, made of high-quality nylon, is the powerful choice for fastenings in solid and perforated substrates. Special features: 4-way expansion for high load values. Anti-rotation lugs for screw retention and easy installation. Greater anchorage depth for better force transmission in perforated substrates and aerated concrete. A clearly noticeable tightening torque prevents overtightening of the screw.
