Simpson Strong-Tie Short Drop-In Anchor DIA37S

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-inch and 3/4-inch coil threaded rod. Short Drop-In anchors are for use in solid and hollow concrete. The short length permits shallow embedment that helps to avoid drilling into rebar or pre stressing strands. The wide surface flange enables the Short Drop-In to be installed in deep or bottomless holes. Fixed-depth drill bits are also available to take the guesswork out of drilling to the correct depth for these 3/8-inch and 1/2-inch Short Drop-Ins. Using the fixed-depth bit drill bit prevents over drilling, which saves time and prolongs bit life.
