Overview

A blue zinc plated drop-in expansion anchor is a reliable and versatile female anchor designed for secure fastening into solid concrete. It consists of a pre-assembled anchor unit with an internal taper that accepts a setting tool to expand the anchor within a drilled hole. The blue zinc plating provides a degree of corrosion resistance, making it suitable for interior applications in dry conditions where a flush, tamper-resistant, and high-quality anchoring solution is required.

Definition

A blue zinc plated drop-in expansion anchor is a female concrete anchor constructed from steel and finished with a blue zinc coating for moderate corrosion resistance. This anchor is characterized by its internal threading and an expandable cone at the bottom, which is driven upwards by a setting tool after the anchor is “dropped in” flush with the concrete surface. This action expands the anchor against the concrete, creating a strong, secure, and flush-mounted attachment point for threaded rods or bolts.

Advantages

• Flush Installation: The anchor sits flush with the concrete surface once installed, providing a clean appearance and eliminating trip hazards.
• Internal Threading: Offers a reusable threaded socket for machine screws, bolts, or threaded rods, allowing for easy attachment and removal of fixtures.
• Tamper-Resistant: Once set, the anchor provides a secure and tamper-resistant connection, as the expansion mechanism is internal.
• Moderate Corrosion Resistance: The blue zinc plating offers protection against rust in typical indoor, dry environments.
• Easy Setting: The setting process is straightforward using a specific setting tool, ensuring proper expansion and grip within the concrete.
• Versatile Applications: Suitable for a range of overhead and vertical applications where a strong, threaded connection is needed in concrete.

Applications

• Overhead Applications: Widely used for suspending electrical conduit, sprinkler systems, HVAC ducts, and other overhead fixtures from concrete ceilings.
• Pipe and Cable Support: Provides secure attachment points for pipe hangers, cable trays, and communication lines in commercial and industrial buildings.
• Fire Sprinkler Systems: A common choice for installing components of fire suppression systems due to its reliability and flush finish.
• Suspended Ceilings: Used to attach hanger wires and other components for drop ceilings in various building types.
• Rack and Shelf Installation: Suitable for mounting shelving units, storage racks, and light to medium-duty fixtures to concrete walls or floors.
• Temporary and Permanent Fixtures: Offers a dependable anchor for both temporary installations where components might need to be removed and reattached, as well as permanent fixtures.
