Simpson Strong-Tie STB2-50334 Strong-Bolt® 2 — 1/2-in. x 3-3/4-in. Wedge Anchor (25-Qty)

The Strong-Bolt is wedge anchor designed for optimum performance in both cracked and uncracked concrete: a requirement that the 2009 IBC places on post-installed anchors. The Strong-Bolt anchor is proven to offer increased reliability in the most adverse conditions, including cracked concrete under static and seismic loading. The proprietary tri-segmented clip has dual undercutting embossments on each segment which enable secondary or follow-up expansion if a crack forms and intersects the anchor location.
