Single Expansion Anchor

    During installation, fix the zinc alloy single expansion anchor at the open end of the pre drilled hole, insert the end with the expansion cone nut into the base material, and gently tap with a hammer to make the open end of the anchor body flush with the surface of the base material, and move the fixed object to align with the anchor hole. Insert the appropriate type of bolt through the object being tightened and insert the anchor. Turn the bolt head clockwise until the anchorage is fully seated. To avoid bolts not being tightened as this may result in reduced or even non-existent retention values. 

    Single expansion shield anchor is also called mechanical bolt anchor or concrete single expansion anchor. It has a conical expanded nut with American standard inch internal thread, which is suitable for installation from the light to medium loading place, used for the masonry,concrete or brick and other base materials. Zamac anchors have strong corrosion resistance. A conical expaned nut and a two piece of expansion shields are pre assembled into an expansion anchor. To use galvanized carbon spring steel wire or steel strip to hold the two-piece shields together. When the bolt is inserted into the fixture, the bolt expands and rotates clockwise, resulting in friction. 

     There are two varieties of zinc alloy single expansion anchor series, with obvious difference. In the different assembly positions of conical expansion nut, one type of conical expansion nut is external, and the sizes available are 3/16 ", 1/4", 5/16", 3/8", 1/2 ", and the other type is built-in, with the size specifications of  1/4 ", 5/16", 3/ 8", 1/2",5/8" and 3/4".

     These single expansion shield anchors must be used with the machine bolts and can be removed if necessary, but the anchor body is disposable. Due to the characteristics of the zinc alloy material used, the product has strong corrosion resistance and rust proof function.

单膨胀锚用于坚硬、密实的材料，双膨胀锚用于软材料或强度可疑的地方。两个锚之间的最小距离为10个锚直径，锚与边缘之间的最小距离为5个锚直径。

     The single expansion anchor is used for hard and dense materials, and the double expansion anchor is used for soft materials or places with suspicious strength. The minimum distance between two anchors is ten anchor diameters, and the minimum distance between anchors and edges is five anchor diameters.

单膨胀锚用于带有机械螺钉或机械螺栓的基层结构中，这些螺钉或螺栓暴露在振动或侧压力下。锥形膨胀螺母在拧紧时会沿螺栓向上攀爬，从而使护盾体扩张，产生膨胀功能。在不影响锚固系统的持力的情况下，可以拆卸和更换螺栓。

     Single expansion anchors are used in base structures with mechanical screws or bolts that are exposed to vibration or lateral pressure. The conical expansion nut will climb up along the bolt when tightening, so as to expand the shield body and produce expansion function. The installed bolts can be removed and replaced without affecting the bearing capacity of the anchorage system.
