Wedge Anchor with Nut S-KAK Sormat

The wedge anchor with nut S-KAK Sormat is supplied with a washer. The expansion element is a movable sleeve on the anchor’s conical tail. The anchor is designed for through-fastening of heavy elements and for securing structures in cracked and non-cracked (crack-free) concrete, solid brick (max. ø M8), and natural stone. It may be used in industrial settings and marine climates, provided corrosion resistance is checked regularly. The anchor is placed into a pre-drilled hole, driven in with a hammer, and tightened with a wrench.

Fasteners of the same type include screw anchors RA (electro-galvanized) and RAR (stainless steel). These anchors are fitted with a countersunk-head screw, which allows their use when installing window and door frames. As the screw is tightened, the anchor becomes firmly fixed in the hole.
