Simpson Strong-Tie Strong-Bolt 2 3/4″ x 5-1/2″ Wedge Anchor 10-Pack

Description

Product Overview

The Simpson Strong‑Tie Strong‑Bolt 2 wedge anchor is engineered for demanding concrete fastening tasks where strength, durability, and reliability are paramount. Measuring 3/4″ in diameter and 5‑1/2″ in length, each anchor features a plain washer head and a round shape that distributes load evenly across the installation surface. Constructed from high‑grade steel with a zinc finish, the anchors resist corrosion while maintaining the mechanical properties required for both static and seismic loading conditions. The package includes ten individually packaged anchors, each weighing approximately 0.743 pounds, for a total package weight of 7.43 pounds, making handling and inventory management straightforward for contractors and DIY enthusiasts alike.

Designed in compliance with ACI355.2 and AC193 testing standards, these anchors have been qualified for use in cracked and uncracked concrete as well as masonry applications. The chamfered top of each bolt prevents mushrooming during installation, ensuring a secure fit even in high‑stress environments. With a maximum shear strength of 31,000 psi, the Strong‑Bolt 2 provides the confidence needed for critical structural connections, from foundation anchoring to seismic retrofitting projects.

Each anchor is marked with the Global Trade Identification Number 00707392975885 and the manufacturer’s part number STB2-75512R10, facilitating easy identification and traceability throughout the supply chain. The product’s ASIN B079SKFWQL and UPC 707392975885 further simplify online ordering and inventory control for retailers and end‑users.

Usage

The Strong‑Bolt 2 wedge anchor excels in a variety of concrete applications, ranging from residential deck anchoring to commercial structural steel connections. Its 3/4″ diameter is compatible with a 0.88″ groove diameter, allowing for a secure embedment depth that maximizes load transfer. Whether you are installing overhead lighting fixtures, securing handrails, or anchoring heavy equipment to a concrete slab, this anchor delivers consistent performance. The zinc coating provides additional protection against moisture and chemical exposure, extending the service life of the fastener in outdoor or industrial environments.

For seismic‑critical projects, the anchor’s qualification for design categories A through F ensures compliance with building codes that demand resilience under earthquake loading. Installers can rely on the anchor’s ability to handle both vertical and horizontal forces, making it suitable for bracing, shear wall connections, and other structural reinforcement tasks. The product’s straightforward installation process—drill, insert, and tighten—reduces labor time and minimizes the risk of installation errors.

Because the anchor is supplied in a 10‑piece box, it is ideal for both small‑scale repairs and larger construction contracts. Contractors can efficiently allocate anchors to multiple job sites, and the clear labeling of each unit simplifies on‑site verification. The anchor’s compatibility with standard concrete drilling equipment further streamlines the installation workflow.

FAQ

What concrete thickness is required for proper installation?

The anchor is designed for use in concrete slabs at least 2 inches thick. For optimal shear performance, ensure the embedment depth matches the manufacturer’s recommended specifications, typically 1.5 to 2 inches depending on load requirements.

Can the Strong‑Bolt 2 be used in cracked concrete?

Yes. The anchor is listed for both cracked and uncracked concrete applications. Its wedge design allows it to expand and lock securely even when the surrounding concrete has minor cracks, maintaining the intended load capacity.

Is a special tool required to install these anchors?

No special tools are needed beyond a standard hammer drill with a 3/4″ masonry bit, a wrench or socket set for tightening, and a torque wrench to achieve the recommended installation torque. The plain washer head simplifies the tightening process.

How does the anchor perform under seismic conditions?

The Strong‑Bolt 2 is qualified for seismic design categories A through F, meaning it can withstand the cyclic loading associated with earthquakes. Its tested performance under both static and dynamic loads ensures compliance with seismic building codes.
