Expansion Shield Anchor
.png)
Expansion shield anchors are heavy‑duty masonry anchors designed for fastening lag screws, machine screws, and other threaded fasteners into concrete, brick, block, and other solid masonry materials. Made from durable metal alloys, these shields are split into multiple expansion segments that expand outward when the screw is driven in, gripping tightly to the surrounding substrate.
These anchors are ideal for applications where superior pull‑out resistance, vibration resistance, and long‑term durability are required. Expansion shield anchors can accommodate minor irregularities in the drilled hole, making them more forgiving than many other types of masonry anchors. Their mechanical expansion design ensures secure mounting even in softer, brittle, or uneven masonry materials.
