Expansion Shield Anchor, Double, Zinc Alloy (Inch)
Double expansion shield anchors made from zinc alloy provide superior holding strength and expansion reliability in concrete, brick, block, and other solid masonry materials. Engineered with a two‑piece expansion body, these anchors expand evenly along their full length when a machine screw or lag screw is installed. This dual‑expansion design delivers excellent load distribution, exceptional grip strength, and secure performance even in soft, crumbly, or low‑density masonry.
Zinc alloy construction provides durability, vibration resistance, and corrosion protection suitable for indoor, commercial, maintenance, and general construction environments. Double expansion shields are ideal for applications where consistent, uniform expansion is essential for a long‑lasting mechanical bond.

Double zinc alloy expansion shield anchors are commonly used for:
Heavy‑duty shelving & brackets
Machinery & equipment mounting
Electrical & HVAC supports
Plumbing hardware & pipe straps
Handrails, guardrails & safety fixtures
Signage, mounting plates & structural hardware
Furring strips, blocking & framing attachments
Because expansion occurs along the entire body, double expansion shields excel in difficult substrates, including:
Soft brick
Old mortar
Low‑density block
Uneven or over‑drilled holes
This controlled, uniform expansion reduces the risk of cracking masonry or anchor pullout.
Installation is simple:
Drill the recommended hole diameter.
Insert the double expansion shield flush with the surface.
Drive the screw or bolt to activate expansion and secure the anchor.
These anchors allow the use of machine screws or lag screws, providing flexibility across a wide range of industrial, commercial, and construction applications.
