Anchor Bolts & Foundation Bolts

Foundation Bolts & Anchor Bolts for Concrete and Structural Applications

Foundation bolts are the hidden heroes of structural construction, embedded into concrete to anchor structural steel, wood framing, machinery, or heavy equipment. At Fasteners Plus, we offer a full range of anchor bolt solutions designed to meet the performance and code requirements of professional builders, engineers, and project managers. From residential footings to large-scale commercial foundations, our anchor bolts provide the critical connections your build depends on.

Built to Anchor and Built to Last

Our foundation bolt lineup includes everything from traditional L-shaped and J-style anchor bolts to code-compliant pre-engineered anchors like SSTBs and SB series bolts. Need post-installed options? Our collection also includes wedge anchors and threaded rod systems with epoxy or mechanical connections. These products are built to handle vertical, shear, and uplift loads in both cast-in-place and retrofit scenarios.

We also carry accessories and components like coupler nuts, washers, and hold-downs to help streamline your foundation bolt installation and inspection process. Whether you’re working with rebar cages, anchor templates, or prefabricated systems, we’ve got the gear to keep it solid from the base up.

Common Foundation Anchor Bolt Types We Stock

Fasteners Plus carries a deep selection of products including:

• L-Bolts and J-Bolts: Embedded in concrete footings or pads, these classic shapes offer reliable tension anchoring for columns, posts, and framing.
• PAB Anchor Bolts: Ideal for tilt-wall construction and pre-engineered metal buildings, providing stable, code-rated performance.
• SSTB & SB Anchor Bolts: Code-approved anchor systems used with hold-downs and shear wall assemblies in high-load or seismic areas.
• RFBs (Rebar Fastening Bolts): Used in post-installed anchor applications with epoxy to bond into hardened concrete for maximum strength.
• Coupler Nuts (CNW/HSCNW): Designed for connecting threaded rods in anchor bolt extension and repair projects.
• Wedge Anchors: Heavy-duty post-installed anchors (or "dry-set") used in solid concrete; ideal for structural retrofits, machinery anchoring, and high-load fastening where cast-in-place bolts weren't used.

Frequently Asked Questions About Foundation Bolts

What are foundation bolts used for?
Foundation bolts are embedded in concrete to anchor structural elements, such as steel columns, wooden sill plates, posts, or heavy equipment to the foundation. They're essential for resisting vertical and lateral loads in buildings, bridges, and industrial machinery.

What’s the difference between L-Bolts and J-Bolts?
Both L- and J-bolts are designed to be set into concrete, but the shape affects how they hold. L-bolts offer a square bend for strong hold-downs, while J-bolts provide a hook-like profile ideal for resisting pullout. Your selection depends on engineering specs and local code requirements.

How are foundation bolts installed?
Cast-in-place bolts are installed before the concrete is poured, using anchor templates or fixtures to hold them in alignment. Post-installed anchors like RFBs or wedge anchors are installed into cured concrete using hammer drills and bonding agents or mechanical expansion. Always follow manufacturer specifications and check embedment depth, spacing, and edge distance requirements.

Are these bolts code-approved?
Yes. We stock several foundation bolts that meet ICC-ES or IBC code requirements for use in high-wind, seismic, and load-critical zones. This includes SB and SSTB series bolts compatible with Simpson Strong-Tie® systems, as well as PAB anchors for panelized structures.

Can I use wedge anchors instead of cast-in-place bolts?
In some retrofit scenarios, yes. Wedge anchors are often used when cast-in-place bolts weren’t set or need to be repositioned. However, always confirm load requirements and code compliance before substituting anchor types.
