The most versatile injection system with internal thread anchor provides additional variability thanks to flexible disassembly.
The Upat internal threaded anchor UPM-I is an accessory for chemical fixings that offers top flexibility when anchoring using screws with a metric thread or threaded rods since it enables surface-flush removal. This anchor is made from zinc-plated steel and can be used in conjunction with the Upat injection mortars in masonry. The internal threaded anchor is set manually, by lightly rotating it. In solid brick, the injection mortar joins the entire surface of the internal threaded sleeve with the wall of the drill hole. In perforated building materials, the mortar is pressed through the gratings of the anchor sleeve and creates a form fit with the perforated brick. This directs the load into the building material. The system is used particularly frequently with the injection internal threaded anchor UPM-I for the temporary fixing of fixtures.
