Description
Product Overview
When a project calls for a secure connection to concrete, the choice of fastener can make the difference between a lasting installation and a future repair. The Concrete Stud Anchors from Hard to Find Fastener are engineered to meet the rigorous demands of commercial construction, residential renovation, and industrial maintenance. Each anchor measures three eighth by three and a half inches, a size that balances deep embedment with ease of installation. Constructed from high‑grade steel and coated with a zinc finish, these anchors resist corrosion, maintain structural integrity, and provide a reliable load‑bearing capacity even in harsh environments.
Beyond the basic dimensions, the design incorporates a precision‑machined cutting diameter of 0.38 inches, ensuring a snug fit in standard concrete drill holes. The zinc coating not only protects against moisture and chemical exposure but also reduces friction during insertion, allowing the installer to achieve full depth with minimal torque. The package contains six individual anchors, each individually packaged to preserve the coating and prevent damage during shipping.

Usage
These stud anchors excel in a variety of concrete applications. Whether you are mounting a heavy door frame, securing a conduit box, attaching a shelving system, or installing a fire‑rated partition, the anchor delivers a dependable connection point. The zinc‑finished steel construction makes them suitable for outdoor installations where exposure to rain, snow, or salty air is a concern. They are also ideal for indoor settings such as garage walls, utility rooms, and commercial storefronts where a clean, flush finish is desired.
Installation is straightforward for professionals and DIY users alike. After drilling a pilot hole to the recommended 3/8‑inch diameter, the anchor is placed into the hole and driven with a hammer or impact driver until the head sits flush with the concrete surface. The result is a solid, load‑bearing stud that can be used with a variety of nuts, washers, and brackets. Because the anchor is designed for door mounting, it aligns perfectly with standard door hardware, simplifying the process of hanging doors, gates, and panels.

FAQ
What type of concrete is suitable for these anchors?
The anchors are designed for standard poured concrete, including reinforced concrete with rebar. They perform well in both interior and exterior applications as long as the concrete is solid and free of cracks at the installation point.
Do I need a special tool to install the anchors?
No special tools are required. A standard hammer or impact driver, along with a 3/8‑inch drill bit for the pilot hole, is sufficient. The zinc coating reduces friction, making insertion smooth and efficient.
Can these anchors be used in masonry or brick?
While the anchors are optimized for concrete, they can be used in dense masonry or brick when a proper pilot hole is drilled. However, for optimal performance in non‑concrete substrates, consider a masonry‑specific anchor.
What is the load capacity of each anchor?
Load capacity varies based on installation depth and concrete strength. In typical 4000 psi concrete, each anchor can safely support up to 500 lb of tensile load when installed to the full 3‑1/2‑inch length.
Is there a warranty on these anchors?
Yes, Hard to Find Fastener offers a limited one‑year warranty covering material defects and coating failures. Contact our support team with the product details for assistance.
