Tandefio 3/8″ x 5″ Flat Sleeve Anchors 50pcs Zinc Plated Bolts

Description

Product Overview

The Tandefio 3/8″ x 5″ flat sleeve anchor is engineered from high‑grade carbon steel and finished with a zinc‑plated coating that resists rust and corrosion in demanding environments. Its flat‑head design sits flush with the substrate, eliminating protrusion and providing a clean, professional appearance that does not interfere with subsequent construction or equipment installation. Each anchor measures 5 inches in length, offering a longer embedment depth that translates into superior pull‑out capacity compared with standard 4‑inch sleeves. The package contains 50 precisely machined anchors, each with a 3/8‑inch diameter that matches standard drill bit sizes, eliminating the need for additional tooling. Technical specifications include a product dimension of 5.91 x 5.91 x 2.17 inches and a weight of 6.64 pounds per box, making it easy to handle on the job site. The model number CLO‑Tandefio‑2478 is recognized by industry professionals for its reliability and consistent performance across a range of concrete, brick, and masonry applications.

Usage

These anchors are ideal for both residential renovation projects and large‑scale commercial installations. Whether you are securing a heavy‑duty electrical conduit to a concrete wall, attaching a steel support bracket to a brick façade, or anchoring a heavy piece of equipment in a warehouse floor, the flat sleeve anchor delivers the strength and stability required. The zinc‑plated finish makes the product suitable for indoor environments with high humidity, such as basements, as well as outdoor applications where occasional exposure to moisture is expected. Installation is straightforward: drill a hole to the recommended diameter, clean the cavity, insert the anchor, and tighten the bolt until the head sits flush. No additional washers or spacers are needed, which reduces inventory complexity and speeds up the installation process. The design also distributes load evenly across the surrounding material, minimizing the risk of cracking or spalling in brittle substrates. This makes the anchor a preferred choice for contractors working on historic masonry where preserving the integrity of the original material is critical.

FAQ

What substrate thickness is recommended for a 5‑inch flat sleeve anchor?

The anchor is designed for substrates that are at least 2 inches thick. For optimal performance, a minimum concrete thickness of 2.5 inches is recommended, allowing the anchor to achieve its full pull‑out capacity without compromising the surrounding material.

Can these anchors be used in outdoor environments?

Yes. The zinc‑plated coating offers protection against moisture and mild corrosion, making the anchors suitable for outdoor installations where they are not constantly exposed to harsh chemicals or salt spray. For marine or highly corrosive environments, a stainless‑steel variant is advisable.

Do I need a washer when installing the flat sleeve anchor?

No additional washer is required. The flat‑head design provides a built‑in bearing surface that distributes load evenly, eliminating the need for separate washers and simplifying the installation process.

How many anchors can I safely install in a single concrete slab?

The number of anchors depends on the load each will carry and the spacing requirements outlined in the engineering specifications. As a general guideline, maintain a minimum spacing of 3 inches between adjacent anchors to prevent stress concentration and ensure each anchor performs independently.

What is the warranty coverage for these anchors?

Tandefio offers a limited one‑year warranty covering material defects. The warranty does not cover damage caused by improper installation, misuse, or exposure to conditions beyond the intended design parameters.
