Tie-Wire Wedge Anchor

The Simpson Strong-Tie tie-wire anchor is a wedge-style expansion anchor for use in normal-weight concrete or in concrete over steel deck. With a tri-segmented, dual-embossed clip, the tie-wire anchor is ideal for the installation of acoustic ceiling grid and is easily set with the claw of a hammer.

Key Features

  • 1/4" eyelet for easy threading of wire
  • Sets with claw of hammer
  • Tri-segmented clip — each segment adjusts independently to hole irregularities
  • Dual embossments on each clip segment enable the clip to undercut into the concrete, increasing follow-up expansion
  • Wedge-style expansion anchor for use in normal weight concrete or concrete over metal deck


  • Carbon steel


  • Zinc plated


  1. Drill a hole at least 1 1/2" deep using a 1/4"-diameter carbide tipped bit.
  2. Drive the anchor into the hole until the bottom of the head is flush with the base material.
  3. Set the anchor by prying/pulling the head with the claw end of the hammer.
