S-VAM S and S-VAM B Heavy-Duty Anchors

Sormat S-VAM S and S-VAM B heavy-duty metal anchors are used for fastening heavy and medium-heavy structures into hard materials: concrete, brick (max. M8) and natural stone. Thanks to strong and adjustable expansion, the anchors carry significant loads. A dual-cone system and a curved washer ensure reliable fixation of the fastened parts to the base.

The anchor is installed into a pre-drilled hole in the base; it is recommended to clear the hole of dust. As the bolt is tightened, the anchor expands due to the expansion effect and is fixed in the base. Friction holds it in position even under high loads, ensuring the durability of the fastening and its ability to support substantial weight of building structures.

The products are made of high-strength steel with a protective zinc coating, resistant to corrosion from external exposure.
