Fastener Factory Hex Flange Bolt and Nut, Carbon Steel Galvanized Mechanical Sleeve Expansion Wedge Anchor Bolt with Chemical for Concrete

The working principle of the car repair wall anchor is that when installing, the bolt is inserted into the pre-drilled hole and the nut is tightened. When the nut is tightened, the bolt exerts force outward, causing the outer sleeve to expand. This squeezes the slot or cutout of the outer sleeve into the hole, creating a secure connection. The nut on the bolt can be used to adjust the tightness of the connection.
