    Zinc alloy single expansion anchors consist of two tubular shields and a cone nut pre-assembled into an integral unit, which are made of high-quality zinc alloy and manufactured by die-casting machinery. The tubular shield and conical nut are tightly bound together by spring band with spring clamping force. However, another type of zinc alloy concrete single expansion anchor cone nut is built into the lower end of two shields, which are tightly fastened with four clips on their edges, instead of the spring fastening.

    The lower end of the shield surface is designed as a spiral thread to strengthen the friction between the product and the hole wall after the product is embedded in the pre drilled hole, so as to prevent the roduct from falling off, sliding or pulling out from the hole. The integral lug on the tapered nut prevents rotation in the tubular shield during expansion. The single expansion shield anchor is made of precision die-casting zinc alloy, which has anti-oxidation, corrosion resistance, high and low temperature resistance and no rust.      They are usually used for anchoring and fixing the objects from single point anchoring in the concrete, masonry, block and brick base structures with light to medium load strength.

    The size of the inner thread is from 1/4 "to 3/4", and the drilling diameter depends on the outer diameter of the product. During installation, it is necessary to drill a pilot hole for installation. After clamping the installation object, fasten a machine bolt into the anchor body, and move the conical nut to open the two shields to generate expansion force.
