Drop-in anchors are internally threaded drop-in expansion anchors for use in flush-mount applications in solid base materials. Minimum thread engagement should be equal to the nominal diameter of the threaded insert.
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" for flush mounting. Blow the hole clean using compressed air. Overhead installations need not be blown clean.
Insert designated anchor into hole. Tap with hammer until flush against surface.
