MT anchor design and geometry

Shank recess to protect the thread during anchor installation.
Pre-assembled nut with internal thread that allows the screw to be attached, allowing the fastening and joining of removable elements.
Pre-assembled DIN 125 washer ensuring correct pressure on the element to be fixed, with the option of supply in DIN 9021 (wide series) or DIN 440 (for wood) versions depending on the application.
Installation depth mark indicated on the shaft, indicating the depth recommended by the certification for inserting the metal anchor into the drill hole.
The Letter on the shaft identifies the anchor length, allowing us to know its length once installed, and enabling the appropriate selection according to the thickness of the element to be fixed.
Shank edge designed to keep the clip in position during installation.
Expansion system composed of a clip and cone, where the cone retracts and expands the clip to generate pressure against the base material and achieve fastening.
Engraved identification on the clip indicating the model and size of the anchor, facilitating its recognition on site.

Superior performance in loads and distances

With MT male anchors, we increase the maximum recommended loads in non-cracked C20/25 concrete and cracked C20/25 concrete compared to the previous model.
