Frequently Asked Questions
- What drill bit size is required to install the Strong-Bolt 2 5/8 in. wedge anchor?
- The Strong-Bolt 2 5/8 in. x 8-1/2 in. wedge anchor installs with a standard 5/8 in. drill bit and requires a 15/16 in. wrench for tightening, making it compatible with common drill bit and tool sizes.
- Is this wedge anchor rated for seismic applications?
- Yes. The Strong-Bolt 2 is qualified for both static and seismic loading conditions and is code listed for seismic design categories A through F. Its dual undercutting embossments on each clip segment enable secondary expansion if a crack forms and intersects the anchor location, significantly increasing load-carrying capacity under dynamic conditions.
- Can this anchor be used in cracked concrete?
- Yes. The Strong-Bolt 2 is code listed for both cracked and uncracked concrete applications. The dual undercutting clip design allows the anchor to maintain load capacity even if the surrounding concrete develops cracks at the anchor location.
- Why is Type 316 stainless steel used for this anchor?
- Type 316 stainless steel provides superior corrosion resistance compared to standard carbon steel or Type 304 stainless steel, making this anchor well-suited for a wide variety of demanding service environments where long-term durability and resistance to corrosion are critical requirements. All components - including the anchor body, nut, washer, and clip - are manufactured from Type 316 stainless steel.
