Simpson Strong-Tie Drop-In Anchors: Standard, Stainless & Hollow

Drop-In Anchors are internally threaded expansion anchors designed for flush installation in solid concrete and masonry. At Fasteners Etc., Inc., we stock the newly designed Simpson DIAB series, which features an improved plug design that allows for faster installation with fewer hammer strikes. This high-efficiency expansion anchor is available in multiple styles, including short and lipped options, to meet your specific embedment depth requirements.

For specialized applications, consider our hollow drop-in anchor (HDIA) for projects requiring installation into hollow base materials or core planks. These fasteners are ideal for attaching threaded rod for overhead electrical or plumbing runs. Our inventory includes carbon steel with a zinc plated finish, as well as stainless steel options for maximum corrosion resistance.

To ensure a secure connection, always use the appropriate setting tool and a matching SDS carbide drill bit to reach the correct anchor diameter and depth. If your project requires non-standard lengths, you can request a quote from our in-house machine shop to have rods and studs cut to your exact specifications. Browse our full selection of mechanical anchors and anchoring solutions to find the right SKU for your jobsite.
