Expansion Shield Anchors
Expansion shield anchors are used for anchoring into concrete, block, brick, or base materials of questionable strength. They are recommended for shear load and applications where the bolt is subject to vibration or side pressure. Concrete expansion shield anchors are used for light- to heavy-duty applications.

Our Stock of Concrete Expansion Shield Anchors
Single Expansion Shield AnchorsLight-duty single expansion shield anchors require an additional threaded fastener (usually a hex bolt or similar) to expand the anchor and attach fixtures to concrete or materials of unknown holding strength. The secondary fastener can be removed without affecting the expansion shield anchor’s holding strength.
Double Expansion Shield AnchorsIdeal for light- to heavy-duty applications, a double expansion anchor functions similarly to a single expansion shield anchor but with two expanding nuts on each end. When properly installed, these expansion shield anchors can be effectively reused multiple times.
Lag Screw Expansion Shield AnchorsLag screw expansion shield anchors are recommended for light- to medium-duty applications. Long lag screw expansion shield anchors are recommended for softer base materials, and short lag screw expansion anchors are recommended for harder base materials. As the name suggests, a lag screw must be inserted to expand the fastener.
How to Install Expansion Shield AnchorsAll expansion shield anchors can be installed using a simple four-step process:
- Drill a hole in the concrete or other material of the correct size and depth for the anchor.
- Clean all debris from the hole.
- Insert the expansion shield anchor into the hole and gently tap with a hammer until flush with the surface.
- Align your fixture over the anchor, insert the bolt through the fixture, and thread it into the anchor.
