    • An anchor bolt (100) is provided which includes a head (112), a drill portion (120), and an intermediate shank portion (110). The intermediate shank portion has a longitudinal cavity (142) formed therein for receiving a mounting set screw. An external thread (116) is formed on the shank portion for threading the anchor bolt into the wall. The shank portion is divided by a slit (122) into at least one portion (146) and the external thread on the shank portion is divided into a plurality of discrete thread segments by the slit. The drill portion has a cutting edge (136) and at least one flute (134) formed therein which also extends to a drill tip (124) and to a sharpened point (126). The anchor bolt is driven into the wall portion with a screwdriver, and then a mounting set screw is inserted into the longitudinal cavity. When the mounting set screw is inserted into the cavity, the set screw causes a portion of the shank portion to separate from the shank portion to engage with the wall.
    • 提供一种锚栓(100),其包括头部(112),钻头部分(120)和中间柄部分(110)。 中间柄部具有形成在其中的纵向腔(142),用于接收安装固定螺钉。 在所述柄部上形成外螺纹(116),用于将所述锚定螺栓穿过所述壁。 柄部分被狭缝(122)分成至少一部分(146),并且柄部分上的外螺纹通过狭缝被分成多个离散螺纹段。 钻头部分具有切割边缘(136)和形成在其中的至少一个凹槽(134),其也延伸到钻头尖端(124)和尖锐点(126)。 用螺丝刀将地脚螺栓推入壁部,然后将一个固定螺钉插入到纵向腔中。 当安装定位螺钉插入空腔中时,固定螺钉使得柄部分的一部分与柄部分分离以与壁接合。
