Design and geometry

Shaft retracts as thread protection during anchor installation.

Nut. The internal threading makes it possible to fit the screw, facilitating the securing and connection of detachable elements. It is supplied pre-assembled.

Washer. It ensures optimal precision of the element being installed. It is supplied with a pre-assembled DIN 125 washer. Optionally, it can be supplied with DIN 9021 (wide series) or DIN 440 (for wood) washers.

Marked with the installation depth. The line painted on the shaft marks the depth recommended by the approval to insert the anchor into the drill.

MTH anchor shaft lettering indicating its length

The lettering on the shaft indicates its length, letting you know the length of the anchor once installed. It is important to check the thickness to be fastened in order to properly choose the necessary anchor length.

Shaft edge: It allows the clip to be held in position during installation.

Expansion clip and cone: The cone retracts, expanding the clip and exerting pressure on the base material to enable fastening.
