Expansion Shield Anchors
For Greater DiscountsRequest Custom Quote
Expansion anchors are used for anchoring into concrete, block, and brick, or into base materials of questionable strength. They are recommended for shear load and for applications where the bolt is subject to vibration or side pressure. Concrete expansion shield anchors can be used for light- to heavy-duty applications.
Denali Industrial Supply’s huge inventory of expansion shield anchors makes us Anchorage, Fairbanks, and Interior Alaska’s leading supplier. Order today, request a quote, or contact us for more information on our expansion shield anchor options.
Concrete Expansion Shield Anchor Options
We offer single expansion shield anchors, double expansion shield anchors, and lag screw expansion shield anchors. All varieties are available in an array of sizes and are easy to install.
Single Expansion Anchor
In addition to concrete, these light duty anchors can also be installed in soft masonry and materials of unknown holding strength. An additional threaded fastener (usually a hex bolt or similar) is needed to expand the anchor and attach fixtures; the secondary fastener can be removed without removing the expansion shield anchor and without affecting its holding strength. Properly installed anchors can be reused almost indefinitely.
Double Expansion Anchor
Double expansion anchors are ideal for light- to heavy-duty applications. As with a single expansion shield anchor, a double expansion anchor requires hex bolt or other appropriately-sized threaded fastener to expand the sleeve and complete installation. The secondary fastener can be removed without removing the double expansion anchor or affecting its holding capabilities. When properly installed, a double expansion anchor can be reused over and over again.
Lag Screw Expansion Anchors
Lag screw expansion shield anchors are recommended for light- to medium-duty anchoring applications. We stock long and short models—long lag screw expansion shield anchors are recommended for use in softer base materials; short lag screw expansion anchors are recommended for use in harder base materials. As the name suggests, a lag screw must be inserted to expand the fastener and ensure proper installation. The lag screw and fixture can then be removed, leaving the expansion shield anchor in place for future use.
Installing Expansion Shield Anchors
All types of expansion shield anchor can be installed using a simple four-step process:
- Drill a hole in the concrete 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 it is flush with the surface.
- Align your fixture over the anchor, insert the bolt through the fixture, and thread it into the anchor.
