The Duojia “Fish-scale Expansion Sleeve Anchor YZP” is a robust, torque-controlled expansion anchor designed for reliable fastening in a variety of solid base materials, including concrete, brick, and block. Its most distinctive feature is the unique “fish-scale” texture embossed on the expansion sleeve, which is engineered to significantly increase friction and grip within the drilled hole. Made from carbon steel and finished with a Yellow Zinc Plating (YZP), this anchor offers both high strength and enhanced corrosion resistance, making it an essential and versatile solution for construction, industrial, and general-purpose fastening applications.
This anchor has several key design elements that define its function and application.
The anchor achieves its holding power by the expansion of its sleeve. Please note that the installation instructions provided on the source page appear to be incorrect and describe a different type of anchor. The correct mechanism and installation for a sleeve anchor are as follows:
