Steel Wedge Anchor Yellow Zinc Plated

    Concrete wedge anchor can be used as expansion bolt. The types of expansion anchors include pre-assembled matching cylinders and threaded wedge expansion anchors or it is called through bolt anchor . Wedge anchors are of carbon steel and stainless steel construction with different head types and can be used on cracked and uncracked concrete, block, brick and stone surfaces.

锥形锚实现锚固功能的设计要点在于下端的锥形杆体被一个膨胀夹包裹，在被螺母紧固的时候，它受洞壁表面摩擦力的作用下，逐步下滑扩展，达到膨胀的目的。

    The key point of the design of masonry wedge anchor to realize the anchoring function is that the conical rod body at the lower end is wrapped by an expansion clip. When it is fastened by the nut, it will gradually slide down and expand under the action of the friction force of the tunnel wall, so as to achieve the purpose of expansion.

楔形锚栓有镀锌碳钢结构、配外六角螺母和垫圈样式和多种直径从1/4英寸至3/4英寸。可根据规格定制锚固件为OEM市场生产楔形锚固件。 楔形锚通常用于桥面，码头、地铁，混泥土施工场所，墙壁或楼板。它们有镀锌钢、热浸镀锌层和304和316不锈钢等级。

Wedge anchors are available in galvanized carbon steel construction with external hex nut and washer styles and in a variety of diameters from  M6-1/4 inch to M20-3/4 inch. 

     They can be customized according to specifications and wedge anchors are produced for OEM markets. Wedge anchors are usually used in bridge decks, wharves, subways, concrete construction sites, walls or floors. They are available in galvanized steel, hot dip galvanized coating and 304 and 316 stainless steel grades as the different installation application.

楔形锚栓由多种不同类型的材料和涂层制成。碳钢楔形锚栓有镀锌或热浸镀锌两种。不锈钢楔形锚栓采用303/304或316不锈钢制成。从使用角度来说，碳钢镀锌楔形锚栓适合应用于干燥无水分的室内应用。热浸镀锌楔形锚栓可用于室外潮湿环境。303/304不锈钢适合用于潮湿的室内外环境。316不锈钢用于本质上具有腐蚀性的浸没液体环境中，或者具有特殊安装要求的室内环境。近些年，随着环保要求的不断提高，碳钢锥形螺栓表面喷镀达克罗工艺不断涌现，比较适合含盐浓度高和潮湿的环境，其防腐防锈性能比热浸镀锌要好，且环保性能也要高。

     Wedge anchors are made of a variety of different types of materials and coatings. There are two kinds of carbon steel wedge anchor bolts, galvanized or hot-dip galvanized. Stainless steel wedge anchor bolt is made of 303/304 or 316 stainless steel. From the use point of view, carbon steel galvanized wedge anchor bolt is suitable for dry indoor application without moisture. Hot dip galvanized wedge anchor bolt can be used in outdoor humid environment. 303 / 304 stainless steel is suitable for humid indoor and outdoor environment. 316 stainless steel is used in immersion liquid environment which is essentially corrosive or indoor environment with special installation requirements. In recent years, with the continuous improvement of environmental protection requirements, the spray Dacromet process on the surface of carbon steel tapered bolts has been emerging, which is more suitable for the environment with high salt concentration and humidity. Its anti-corrosion and anti rust performance is better than that of hot-dip galvanizing, and the environmental protection performance is also higher.

Installation instruction:

* To drill a hole in the concrete using the suitable diameter and depth for installation.

* Clean the drilled hole inside.

* Put anchor body into the hole.

* Go through the installed hole in the object 

* Hammer the anchor head into the hole.

* Turn hex nut to expand and for anchoring and fixing the object.
