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 this setting tool. Installation instructions with this Set Tool: Drill a hole in the base material using the appropriate diameter carbide drill bit as specified in the table. Drill the hole to the specified embedment depth plus 1/8-inch for flush mounting. Blow the hole clean using compressed air. Overhead installations need not be blown clean.
