The Duojia Lipped Blue Zinc Drop-in Anchor is a high-performance, internally threaded expansion anchor designed for fast, reliable, and consistent fastening in solid base materials like concrete, brick, and stone. Manufactured from high-grade carbon steel, this anchor is distinguished by its protective blue zinc plating and an integrated lip at the top. The lip feature acts as a positive stop, ensuring the anchor sets flush with the surface every time and preventing it from being driven too deep into the hole. The blue zinc coating provides excellent corrosion resistance, making it a durable choice for a variety of indoor and protected outdoor environments. Ideal for both heavy industry and general construction, this “bullet anchor” is engineered to create a strong, permanent, and removable fixture point, offering a perfect blend of user-friendly installation and robust holding power.
The Lipped Blue Zinc Drop-in Anchor is constructed for optimal performance and ease of use. The anchor body is a single piece of carbon steel, featuring four expansion slots and a smooth, internally threaded barrel designed to accept standard metric bolts and rods. A key design element is the integrated lip, or flange, at the top of the anchor, which ensures it sits perfectly flush on the surface of the base material without the risk of over-driving. The anchor’s exterior is textured to enhance its grip and prevent rotation within the drilled hole. Internally, a pre-installed expander plug is positioned at the base. During installation, a dedicated setting tool is used to drive the plug upwards into the anchor’s tapered section, forcing the slotted segments to expand and press firmly against the walls of the hole. This creates a secure, 360-degree frictional hold, providing excellent load-bearing capacity. The blue zinc plating is applied through an electro-galvanization process, creating a uniform protective layer that resists rust and corrosion.

This anchor is defined by several key features that ensure superior performance and installation efficiency. The most prominent feature is the Integrated Installation Lip, which guarantees a consistent and accurate setting depth, making it ideal for overhead applications and preventing anchor loss in oversized holes. Secondly, its Enhanced Corrosion Resistance from the blue zinc plating protects the carbon steel from moisture and oxidation, extending the anchor’s service life and maintaining a clean aesthetic. The anchor provides a High-Strength Frictional Grip through its effective four-way expansion mechanism, delivering reliable pull-out and shear strength for securing heavy loads. Furthermore, the Simple and Fast Installation process—requiring only a drill, a hammer, and a setting tool—significantly reduces labor costs and project time. Finally, its Versatile Internal Threading allows for the use of standard-sized bolts and threaded rods, providing flexibility for attaching various fixtures which can be easily removed or replaced as needed.
The Lipped Blue Zinc Drop-in Anchor is an extremely versatile fastener used extensively across numerous trades and industries. In Mechanical, Electrical, and Plumbing (MEP) contracting, it is the standard for suspending threaded rods to support pipes, HVAC ductwork, cable trays, and electrical conduits from concrete ceilings. In General Construction, it is used for fastening brackets, support ledgers, and handrails to concrete walls and floors. For Industrial Facilities, it provides a secure anchoring point for machinery guards, light-duty equipment, and storage systems. It is also suitable for Fire Protection Systems, where it is used to hang sprinkler pipes and system components. The anchor’s reliability and ease of use make it a preferred choice for any application in solid concrete that requires a strong, flush-mounted, and dependable threaded fixing point.
