Drop-In (DIAS) Short Internally Threaded Anchor

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. 

Key Features

  • Lipped edge eliminates need for precisely drilled hole depth
  • Hand- and power-setting tools available for fast, easy and economical installation
  • Fixed-depth stop bit helps you drill to the correct depth every time
  • Short length enables shallow embedment to help avoid drilling into rebar or pre-stressed/post-tensioned cables
  • Short drop-in anchors include a setting tool compatible with the anchor to ensure consistent installation

Material

  • Carbon steel
     

Finish

  • Zinc plated

Installation

  1. 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.
  2. Insert designated anchor into hole. Tap with hammer until flush against surface.
  3. Using the designated drop-in setting tool, drive expander plug toward the bottom of the anchor until shoulder of setting tool makes contact with the top of the anchor.
  4. Minimum thread engagement should be equal to the nominal diameter of the threaded insert.

Caution

  • Oversized holes will make it difficult to set the anchor and will reduce the anchor’s load capacity
