Description
Product Overview
The Simpson Strong‑Tie SL37300H Sleeve‑All anchor is engineered for demanding concrete applications where strength, durability, and corrosion resistance are paramount. Constructed from Grade 304 stainless steel, the anchor combines a robust hex‑head design with a 3/8‑inch diameter and a 3‑inch embedment length, delivering a secure mechanical lock that resists pull‑out forces even under cyclic loading. The stainless‑steel finish not only protects against rust in humid or coastal environments but also maintains a clean, professional appearance over the life of the installation. Each package contains 50 individually packaged anchors, ensuring consistent performance across large‑scale projects while simplifying inventory management for contractors, facility managers, and serious DIY enthusiasts alike.

Usage
Designed specifically for solid base materials such as poured concrete, masonry, and reinforced stone, the SL37300H anchor excels in a variety of structural and non‑structural applications. Whether you are anchoring heavy equipment, securing handrails, mounting electrical panels, or installing fire‑rated assemblies, the hex‑head provides a reliable drive surface for a 1/2‑inch wrench, allowing quick and accurate installation without the need for specialized tools. The anchor’s expansion mechanism activates as the bolt is tightened, pressing the sleeve against the surrounding material to create a firm, load‑bearing connection that meets FM and UL approval standards. This makes it an ideal choice for commercial construction, industrial facilities, and high‑traffic public spaces where safety and code compliance are non‑negotiable.
Because the anchor is fully threaded with a 3/8‑inch‑16 UNC thread, it accommodates a wide range of fastener lengths and can be paired with compatible nuts, washers, or specialty hardware to meet specific design requirements. The stainless‑steel composition also ensures compatibility with a broad spectrum of chemical exposures, including mild acids, salts, and cleaning agents, reducing the risk of premature degradation. For projects that demand a high degree of reliability, such as seismic retrofits or load‑bearing structural connections, the SL37300H provides the confidence that the connection will perform as engineered throughout the structure’s service life.
Why Choose Us
Choosing the Simpson Strong‑Tie SL37300H means selecting a product backed by decades of industry expertise and rigorous testing protocols. Simpson Strong‑Tie is a globally recognized leader in fastening solutions, and each anchor undergoes comprehensive quality assurance procedures, including tensile strength testing, corrosion resistance evaluation, and dimensional verification, to ensure that every unit meets or exceeds the specifications outlined in the product data sheet. This commitment to quality translates into reduced re‑work, lower maintenance costs, and increased confidence for engineers and installers who rely on consistent performance across every batch.
In addition to the superior material properties, the SL37300H benefits from multiple certifications, including FM and UL approvals, which are essential for projects that must adhere to stringent fire‑rating and safety standards. The anchor’s design also incorporates a patented sleeve‑expansion system that distributes load evenly across the surrounding concrete, minimizing the risk of cracking or spalling in the substrate. This technology, combined with the corrosion‑resistant stainless‑steel finish, ensures that the anchor remains functional and aesthetically acceptable even in harsh environmental conditions such as coastal installations, industrial plants, or outdoor structures exposed to freeze‑thaw cycles.
Our customer support team is dedicated to providing technical assistance throughout the product lifecycle. Whether you need guidance on proper installation torque values, compatibility with specific concrete mixes, or advice on selecting the appropriate bolt length for a given application, our engineers are available to help. We also offer comprehensive documentation, including installation manuals, load tables, and CAD drawings, to streamline the design process and reduce engineering time. By partnering with Simpson Strong‑Tie, you gain access to a network of resources that empower you to complete projects efficiently, safely, and with confidence.
Finally, the value proposition of the 50‑piece pack cannot be overstated. Bulk packaging reduces per‑unit cost, simplifies procurement, and ensures that you have a ready supply of anchors for repetitive tasks or large‑scale installations. This economical approach is especially beneficial for contractors who manage multiple job sites, as it minimizes the need for frequent re‑ordering and helps maintain project schedules without interruption.

FAQ
What type of concrete is suitable for this anchor?
The SL37300H is designed for use in solid, poured concrete with a compressive strength of at least 3,000 psi. It works well in both new construction and existing structures, provided the concrete is free of cracks and the hole is drilled to the recommended diameter and depth.
Can this anchor be used in masonry or stone?
While the anchor is optimized for concrete, it can also be installed in high‑strength masonry or stone when a proper pilot hole is drilled and the substrate meets the required load criteria. For best results, consult the installation guide to verify compatibility with the specific material.
Is a special drill bit required for installation?
Yes, a carbide‑tipped drill bit sized to match the anchor’s recommended hole diameter (typically 5/16 inch for the SL37300H) should be used. This ensures the sleeve expands correctly and achieves the intended pull‑out strength. Always clean the hole of dust and debris before inserting the anchor.
How do I determine the correct bolt length to use with this anchor?
The bolt length should be selected based on the embedment depth of the anchor plus the thickness of the material being fastened, plus an additional 1/4 inch to allow for proper thread engagement. For a 3‑inch embedment, a 4‑inch to 5‑inch bolt is commonly used, but refer to the load tables for precise recommendations.
What warranty does Simpson Strong‑Tie provide for this product?
Simpson Strong‑Tie offers a limited warranty that covers material defects and workmanship for a period of one year from the date of purchase. The warranty does not cover damage caused by improper installation, misuse, or exposure to conditions beyond the product’s specified limits.
