The surface by the dacromet coating is better than the zinc plating and the HDG . The materials used to produce is the carbon steel or the stainless steel for the anchor body or the Clip according to the customers' requests.
Wedge anchor bolt or through bolt is a heavy mechanical expansion anchor designed to install objects in solid concrete base or grouted masonry. One end of the anchor body is externally threaded and pre assembled with nut and washer.The anchor body is made of carbon steel or stainless steel with an expansion clamp.
During installation, after the anchor body is driven into the pre drilled hole with the same diameter as the anchor body, the nut is tightened to the required torque value to set the anchor to obtain the best anchoring performance. The head of one end of the anchor body with external thread is higher than external threads pattern. One is to protect the external threads pattern when hammering the head of the anchor body into the pre drilled hole; the other is to identify the length of the wedge anchor bolt, so that an English letter representing the length can be printed on the head. This identification letter can be seen on the top of the anchor to determine the length of the anchor after installation.
It provides a safe anchorage solution and ideal choice for the installation objects in concrete. When installed in pre drilled holes in concrete and tightened, wedge anchors expand and anchor the installation. Metric and English specifications, various diameters and lengths are available to accommodate a variety of concrete fastening applications.
* carbon steel and stainless steel, zinc galvanized, hot dipped galvanized or dacromet coating.
* Suitable for anchoring objects in solid or grouted concrete masonry substrate.
* A safe expansion anchor body is formed when the expansion clamp expands during installation.
The one-piece grip ensures uniform holding capacity, which increases with the tension applied as the nut is tightened. Most of the anchoring objects used in pouring concrete are mechanical expansion anchors. Wedge anchors provide a simple and fast installation operation, drilling, cleaning hole dust, anchoring and fastening.
The diameter of the borehole is the same as that of the wedge anchor. For example, for a dia. 12mm wedge anchor, you will use a 12mm bit. The drilling depth is at least 12 mm higher than the expected depth. If you want, you can drill all the way to the board, in which case, if you want to remove the anchor, you can remove the nut and hit the base surface hard. It is designed for the application of cast concrete rather than hollow base. The drill bit matches the diameter of the anchor. Drill 12mm at the required embedment. Install in accordance with manufacturer's recommendations, usually drilling, cleaning, hammering and tightening to recommended torque. Minimum embedment guidelines should also be followed.
The conventional surface treatment is zinc galvanizing, and mechanical galvanizing and stainless steel wedge anchors are also available. Wedge anchors can be installed by means of clamps. Assemble the nut and washer until the nut is flush with the top of the anchor and insert into the pre drilled hole. Hammer the anchor bolt into the hole until the washer is flush with the surface of the fixture. Tighten the nut to allow the anchor bolt to expand. Good shear value. Stainless steel wedge anchors are corrosion resistant and are ideal for applications requiring chemical resistance. Stainless steel has a slight magnetism.
The design of the concrete wedge anchor allows it to hold the fixture in the concrete. Concrete wedge anchors can be used for many applications if the foundation material is solid concrete. Unlike many other concrete fasteners, wedge anchors cannot be used for bricks or blocks. Wedge anchor bolts work mainly by inserting holes into the concrete. The wedge anchor is then expanded to wedge itself firmly into the concrete wedge. The anchorage consists of two independent components, which are permanently pre assembled into a unit. The first one is a carbon steel rod, the length of the threaded part. The other end / installed end of the expansion anchor has a necking diameter or conical space that tapers outward gradually back to the full end diameter of the rod. The second part of the concrete wedge anchor is a steel slip or sleeve that is permanently assembled around the tapered part of the rod. Each wedge anchor also requires a nut and washer to complete the installation.
