Hot dipped galvanized (HDG) wedge anchor with the high rust proof features stamped SS 304/316 clip or the steel clip, The anchor body is made by the carbon steel from 4.8 gr. to 8.8 gr. and the heat treatment.
Hot dipped galvanized wedge anchor is a kind of mechanical expansion anchor made of metal material. It is composed of four parts: external thread anchor body, expansion clamp, nut and washer, which provides the highest and most consistent retention value of mechanical expansion anchor bolt.
The head of one end of the external thread is higher than the thread pattern, and the design purpose is to not harm the thread when hammering the head to embed in the pre drilled hole. It is mainly used in the installation of anchoring and fixing the objects and equipment of concrete base. The surface treatment of carbon steel wedge anchor is zinc plating, hot dipped galvanized(HDG) or dacromet coating. Stainless steel wedge anchors are available in grades 304 and 316.
According to different construction applications, wedge anchor bolt is made of different materials, standard galvanized steel wedge anchor bolt is used for dry indoor; hot dipped galvanized wedge anchor is used for humid indoor and outdoor environment; 303 / 304 stainless steel wedge anchor is used for wet environment that may be immersed in water. 316 stainless steel wedge anchor is used in contaminated places containing salt water or chlorine gas, and can also be used in sites with high-grade installation and decoration requirements.
The installation instruction:
* The cemented carbide bit with the same diameter as the installation anchor is pre drilled a hole in the concrete substrate.
* Drill hole to the specified embedment depth and clean the interior of pre drilled holes.
* Assemble the anchor with the nut and washer so that the top of the nut is flush with the top of the anchor. Pass one end of the anchorage with expansion clamp through the pilot hole of the installation object until the washer and nut are close to the object.
* Tighten the nut to the required installation torque.
Concrete wedge anchor is used in solid concrete and consists of anchor body, expansion clamp, nut and washer. The anchor body is threaded and can be installed by pre drilling into the concrete. All wedge anchors require holes equal to the diameter of the wedge anchors installed.
