Lag Screw Expansion Shield

    Lag screw expansion shield anchor is specially designed for mortar joints of concrete, block and brick and soft base course. They are made of two pieces of heavy zinc alloy shields, which are combined by locking clips. They have non internal thread, so they need to be fastened with lag bolt to realize expansion function.

产品有2种品种，长型和短型。它们设计的原理和使用功能一样，长度不一样，相同规格的外径和钻孔外径一样。在软质或弱砌体结构中安装锚固时，长型可发挥更好的强度。但在较硬性的砌体结构中，由于钻孔深度比较浅，短型不但能缩短钻孔时间，而且能实现更好的膨胀系数。

    There are two kinds of products, long style and short style. Their design principle and function are the same, the length is not the same, the outer diameter of the same specification and the outer diameter of the drilling hole are the same. When they are installed in the soft or weak masonry structure, the long style can play a better strength. But in the hard masonry structure, because of the shallow drilling depth, the short style can not only shorten the drilling time, but also achieve better expansion coefficient.

拉力螺钉护罩锚定尺寸规定为螺钉尺寸（直径）x 锚定长度。无论长型和短型，都有提供尺寸规格1/4“-3/4”.安装时，钻一个比锚体长度深13mm左右的安装洞孔，用锤钻和尺寸正确的硬质合金钻头在基材上钻一个孔，清除洞孔内的渣土杂质，将锚具插入孔中，用锤子敲打紧固件，埋入锚体使有锁扣的一端朝上放置，并将锚端口和基层面平齐或者略微低点放置，将固定物放在锚上，并将尺寸合适的拉力螺钉穿过固定物拧入锚体中

    The anchor size of lag screw shield is specified as screw size (diameter) X anchor body length. For both long and short styles, the size are available 1/4"- 3/4". During installation, drill an installation hole about 13 mm deeper than the length of the anchor body. Drill a hole on the base material with hammer drill and correct size cemented carbide drill to remove the residue and impurities in the hole. Insert the anchor body into the hole, knock it with a hammer, embed it into the anchor body, and place the end of the anchor with the lock locking clips upward,Place the anchor flush with the base course or slightly lower, place the anchor on the anchor, and screw the lag screw of appropriate size through the anchor into the anchor body

安装在砂浆接缝中时，旋转锚固件，使其在砌块或砖块上膨胀，而不是在砂浆上膨胀。使用一个匹配的拉力螺钉，使其完全接合LAG膨胀的整体长度。

    When installed in mortar joints, rotate the anchors so that they expand on the block or brick rather than on the mortar. Use a matching lag screw to fully engage the overall length of the lag expansion.

***The Long Style and Short Style are  available.
