DROP-IN Internally-Threaded Expansion Shell Anchor

Drop-in anchors are internally-threaded, deformation-controlled expansion anchors with a preassembled expander plug, suitable for flush mount applications in solid base materials. The anchor is set by driving the expansion plug towards the bottom of the anchor using the setting tool. Drop-in anchors are also available in coil-threaded versions for 1/2" and 3/4" coil threaded rod.

The Lipped Drop-In (DIAL) features a lip at the top of the anchor body that keeps the top of the anchor flush with the concrete. This eliminates the need for precisely drilled hole depths and allows for easier flush installation, consistent embedment and uniform rod lengths.

The Short Drop-In Anchor (DIAS) is for use in solid and hollow concrete. The short length enables shallow embedment that helps avoid drilling into rebar or prestressed or post-tensioned cables. The wide surface flange allows the DIAS to be installed in deep or bottomless holes.
