Simpson Strong-Tie 3/4" x 8" RFB Grade 55 Retrofit Foundation Anchor Bolt - Zinc Plated
Specifications
When a foundation needs a new connection point that was never poured into the concrete, the RFB Grade 55 retrofit anchor bolt gives you a straightforward way to add one. Unlike an L-bolt or J-bolt that has to be set before the pour, this precut threaded rod installs directly into existing, cured concrete or masonry with a Simpson Strong-Tie anchoring adhesive. It ships clean and oil-free with a matching nut and washer, and both ends are stamped and color-coded yellow so you can confirm grade at a glance, on the truck or after the inspector shows up. For sill plate reattachment, cripple wall strengthening, and general foundation upgrade work, it's a dependable way to build a mechanical connection into concrete that's already in the ground.
Key Features
- Precut, oil-free threaded rod supplied complete with matching nut and washer
- Grade 55 carbon steel construction for added strength over standard-grade retrofit rod
- Zinc plated finish for corrosion resistance in typical above-grade and protected applications
- Yellow color coding and end stamping for fast grade identification on the job and at inspection
- Installs into cured concrete and masonry, no need to set anchors before the pour
- Available across a range of diameters and lengths to match your project specs
Applications
- Sill plate to foundation attachment
- Seismic retrofit and cripple wall strengthening
- Foundation upgrades on existing homes
- General structural repairs into concrete or masonry
- Remodel and foundation repair jobs needing a new anchor point after the fact rather than at the time of the pour
Installation
Drill the anchor hole to the diameter and embedment depth called out in the current Simpson Strong-Tie adhesive anchoring documentation for your base material, then clean the hole thoroughly before installing. Inject the approved Simpson Strong-Tie anchoring adhesive and seat the RFB bolt to the specified embedment depth. The witness hole in the rod lets you confirm adhesive reached the top of the anchor before it cures. Once cured, add the washer and nut and torque to the connection's design requirements. Always confirm hole prep, adhesive selection, embedment, and edge/spacing distances against current manufacturer documentation, project specs, and local code before installing, and consult a qualified professional for engineered or seismic retrofit applications.
