Product Description
The Simpson Strong-Tie® Strong-Bolt® 2 wedge-type expansion anchor is an optimal choice for high performance even in seismic and high-wind conditions. Dual undercutting embossments on each clip segment enable secondary expansion should a crack form and intersect the anchor location; this feature significantly increases the ability of Strong-Bolt 2 to carry load if the hole expands. The Strong-Bolt 2 is available in zinc-plated carbon steel, mechanically galvanized carbon steel, and Type 304 and Type 316 stainless steel.

Design Information and Load Tables
Caution
- Do not use an impact wrench to set or tighten the Strong-Bolt 2 anchor
- Oversized holes in the base material will make it difficult to set the anchor and will reduce the anchor's load capacity
Installation
- Drill a hole in the base material using a carbide drill bit the same diameter as the nominal diameter of the anchor to be installed. Drill the hole to the specified minimum hole depth, and blow it clean using compressed air. (Overhead installations need not be blown clean.) Alternatively, drill the hole deep enough to accommodate embedment depth and dust from drilling.
- Assemble the anchor with nut and washer so the top of the nut is flush with the top of the anchor. Place the anchor in the fixture, and drive it into the hole until the washer and nut are tight against the fixture.
- Tighten to the required installation torque.
