Dottie DOTDA-38 3/8 Inch Drop in Anchor 3/8-16 Concrete Anchor

Product Description

The Dottie DOTDA-38 is a 3/8 inch drop in anchor designed for secure fastening in concrete and masonry applications. This steel anchor is a trusted solution used by electricians, contractors, and trade professionals who need a reliable hold in poured concrete, block, or brick. The drop in anchor design allows for flush installation, meaning the anchor sits inside the drilled hole rather than protruding above the surface. This makes it ideal for applications where a clean, low-profile mounting point is required. The DOTDA-38 accepts a 3/8-16 threaded rod or bolt, which is a common thread size used across electrical conduit supports, pipe hangers, equipment mounting brackets, and structural attachments. To install, drill a 1/2 inch diameter hole into the concrete surface to the required depth. Drop the anchor into the hole, place the required setting tool AT38 over the anchor, and strike with a hammer until the anchor is fully set and the internal expansion mechanism engages with the surrounding concrete. Once set, the anchor provides a strong, stable connection point. One of the practical advantages of this anchor type is that the fastening bolt or screw can be removed and reinserted without compromising the anchor itself. Any head style bolt or threaded rod with a 3/8-16 thread pitch can be used with this anchor. This flexibility makes it a go-to choice for situations where equipment may need to be repositioned or serviced over time. The anchor performs consistently across a range of concrete strengths, making it suitable for both new construction and retrofit installations. Trade professionals rely on drop in anchors like the DOTDA-38 for overhead conduit runs, mechanical equipment pads, suspended ceiling systems, and any application requiring a permanent, load-bearing anchor point in concrete.

• Steel construction provides consistent performance across a range of concrete and masonry strengths including brick
• Accepts 3/8-16 threaded rod or bolt with any head style for installation flexibility
• Bolt or screw can be removed and retightened without disturbing the set anchor
