The Simpson Strong-Tie Strong-Bolt 2 Wedge Anchors are fully assembled, high-performance mechanical anchors designed for consistent, reliable anchoring into cracked and uncracked concrete. With a trusted reputation in seismic and high-load environments, these anchors meet ICC-ES code requirements (ICC-ES ESR-3037) and are engineered for both strength and ease of use.

Each anchor includes the body, nut, and washer—preassembled for fast installation right out of the box. Available in multiple diameters, lengths, and finishes, they’re ideal for a wide range of structural and non-structural applications.

Key Features

• Code-Compliant: ICC-ES ESR-3037 approved for use in cracked and uncracked concrete, seismic and wind loading.
• Fully Assembled: Preassembled with nut and washer to reduce installation steps and improve job site efficiency.
• Tapered Expansion Clip: Ensures consistent holding power during seismic activity or dynamic loading conditions.
• Versatile Finish Options: Choose from zinc-plated for dry indoor environments, hot-dip galvanized for added corrosion resistance, or stainless steel for demanding exterior and marine applications.
• Stamped Head Markings: Easy identification for inspection and compliance.

Common Applications

• Structural steel base plates
• Racking and shelving systems
• Concrete formwork and equipment anchoring
• Mechanical, electrical, and plumbing supports
• Light poles, handrails, and safety barriers

Installation Tips

1. Drill a hole in the concrete using a carbide-tipped bit the same diameter as the anchor.
2. Clean out the hole to remove dust and debris for optimal expansion.
3. Insert the anchor through the fixture and into the hole until the washer sits flush.
4. Tighten the nut to set the anchor in place—torque values vary by size (see Simpson Strong-Tie installation guide for full specifications).
