Overview

The Minerallac Company 77156US is a heavy-duty 5/8" x 3-1/2" stainless steel wedge anchor designed for permanent, high-strength fastening in concrete, masonry, and stone applications. This four-piece anchor assembly features a mechanical wedging mechanism that expands at the base to create a secure, vibration-resistant hold with superior shear strength compared to light and medium-duty expansion anchors. Constructed from 304 stainless steel, the 77156US resists corrosion in wet, outdoor, and chemically aggressive environments, making it ideal for industrial, construction, and infrastructure projects requiring long-term reliability. Key specifications include a 5/8" diameter, 3-1/2" length, 2-3/4" minimum embedment depth, and 11 threads per inch with a coarse thread type. The anchor's full-contact expansion design ensures maximum load distribution and stability in heavy-duty applications. With a thread length of 4-3/8" and a drill size of 5/8", this wedge anchor is optimized for compatibility with standard concrete and masonry drilling equipment. Applications include securing structural components, machinery mounts, railings, and equipment in concrete foundations, walls, and floors. The 304 stainless steel construction provides excellent resistance to corrosion, pitting, and rust, ensuring durability in harsh conditions such as marine environments, chemical processing facilities, and outdoor installations. Unlike bottom-bearing anchors, the 77156US does not require a solid base, making it suitable for use in hollow or cracked masonry. Each anchor is precision-engineered to meet the demands of heavy-duty fastening applications, providing a reliable solution for structural and industrial projects.
