Zinc alloy lag screw shield anchors are designed to be used for anchoring and fixing the objects in the concrete, masonry or brick base structures. It is made of high quality zinc alloy materials made by zinc alloy die-casting machine. It is composed of two heavy-duty zinc alloy shields with two small locking clips fixed together. The surface of the shield is designed to be threaded with different heights, so as to produce better friction with the pre-drilled hole wall and enhance the expansion coefficient. The interior of the shield is designed as a protruding thick plate armor, in order to enhance the tightening force when the lag screws are fastened inside, so as to avoid loosening.
There are two types of lag screw expansion shield anchors, one is the short type, which is suitable for the hard masonry, and the long type is suitable for soft masonry. They are available in short and long styles from the sizes from 1/4" to 3/4".They need to be installed with lag screws to expand the anchor body.
It is a screw type anchor designed for tension bolts. Suitable for mortar joint of concrete and block or brick wall. In hard masonry materials, short lag screw anchors are used to reduce drilling time. The long type is used for soft or weak masonry to give full play to its strength.
The zinc alloy material of lag shield anchor has good anti rust and anti-corrosion functions. There are short and long designs. Heavy internal thread is used for fastening and inserting tension bolts to fix objects when masonry and concrete are installed on site. The installation position is equal to the surface of the substrate. After installation, the fixed object can be removed because the lag screw shields are still in the concrete and can be removed by unscrewing the removal screw.
Used in concrete, masonry or brick substrate to fix the objects.
Consisted of two heavy duty zinc alloy shields held together by two small locking clips.
The short style for hard masonry, the long style for soft masonry.
To install with the lag screw to expand the anchor body.
The special style can be made according to sketch or sample.
