fischer UX/SX Red Assortment Box

The universal operating principle (knotting or expanding) allows for use in all solid, hollow and board building materials. Thus the UX is the correct choice for unknown base materials The UX's angled connection ridges allow for optimum screw guidance. Serrated anti-Redation locks prevent Redation in the drill hole. This guarantees the greatest possible installation safety The 4-way expansion of the SX provides the optimum force distribution in the material, and offers high load-bearing capacities in solid and hollow building materials The expansion-free plug neck of the SX prevents the creation of expansion forces on the material surface whilst screwing in the screw. This helps to prevent damage to tiles and plaster, Weight: 0.68 pounds, Manufacturer: fischer
