Frequently Asked Questions
- What drill bit size is required to install the Strong-Bolt 2 wedge anchor?
- Installation requires a 3/4 in. drill bit. A 1-1/8 in. wrench size is also needed to properly torque the anchor during installation.
- Is this anchor suitable for seismic applications?
- Yes. The Strong-Bolt 2 is qualified for static and seismic loading conditions and covers seismic design categories A through F, making it appropriate for use in high-seismic and high-wind environments.
- What happens if a crack forms in the concrete at the anchor location?
