Anchor point-made of carbon steel or stainless steel; its one end is twisted a part of its length, and its diameter is limited, while the other end of the cone gradually reduces to the nominal diameter.
Expansion clip-permanently fixed to the anchor near the neck neck area.
Nuts-National standard coarse hexagon nuts; carbon steel and galvanized or stainless steel.
Washers – SAE standard washers; carbon steel and galvanized or stainless steel.
Wedge anchors can only be installed in solid concrete, and cannot be used for other basic materials such as bricks or CMU. Wedge anchors are designed for permanent access to concrete holes.
A very simple mechanism can achieve excellent consistent hold values in concrete. After inserting into the concrete hole, turn the nut clockwise. This operation pulls the anchor body upward, causing the expansion clip to slide down the tapered working end of the wedge anchor. The clamp is then expanded and wedged between the anchor and concrete.
