    Concrete through bolts , through bolt anchor or through bolts is generally called wedge anchor in british countries. Wedge anchors include deeper buried carbon steel expansion anchors designed to increase load values and stainless steel xpansion anchors for continuous low temperature and polluting applications. The wedge-shaped plug-in anchor bolt can achieve greater tensile strength than the ordinary plug-in anchor, and is suitable for holes with unknown depth. Mechanical expansion anchors are ideal for fixed installation applications where the anchor spacing and edge distance are closer than those required for plug-in anchors.

    Steel wedge anchor is composed of a nut, a gasket, an expansion clip and a anchor body. The expanding clip wrapped in the conical rod body will expand along the downward direction of the rod body when it is tightened by the nut, and the expansion force will be generated. There are two types of product specifications: metric and inch system standard, which can meet the needs of different markets.

     Concrete wedge anchors have different types of steel and different coatings. The type of steel and coating to be used depends on the application environment. Galvanized carbon steel wedge anchors are used for dry indoor applications. Anchor bolts, nuts, washers and clamps are made of galvanized carbon steel. Hot dip galvanized wedge anchors are suitable for external applications subject to water or moisture corrosion. Anchor bolts, nuts and washers are made of carbon steel and hot-dip galvanized. The clamp is made of stainless steel. Wedge anchors are also made of two grades of stainless steel. 304 stainless steel has excellent corrosion characteristics and can resist a variety of organic and inorganic chemicals, but it is not used in salt water environment. Anchors are made of 304 stainless steel, nuts, washers and clamps are all made of 304 stainless steel. 316 series stainless steel has the best corrosion resistance and is usually used in harsh environments. 316 stainless steel anchors can also be used in salt water environments. 

    The installation process of wedge anchor bolt is fast and simple. The end of bolt with expansion clamp enters the pre drilling hole in concrete through the installation hole in the installation object. When the nut is tightened, the object is held. Concrete wedge anchors are used to hold fixtures in concrete. The concrete wedge anchor works by inserting it into a concrete drill hole. The wedge anchor is then expanded and wedged firmly into the concrete.

* The solution of anchoring objects is realized

* It is also suitable for use in seismic areas.

* Base structure suitable for concrete and grouted filled blocks.

* High quality materials and surface treatment make it resistant to salt water, fresh water, rain water or marine environment.

* It is used to anchor and fix the logistics equipment to the base surface

* Before installation, the installation holes need to be pre drilled in the concrete according to the outer diameter

Insert the unthreaded end into the mounting hole, then tap the top to embed into the installation depth.

* The washer is close to the installation object, and the nut is tightened to fix the object.
