Drop-In Wedge Anchor

The drop-in wedge anchor is designed for quick installation into concrete or brick bases. Fixation is achieved through an expanding petal sleeve with an internal thread. The anchor is a cylindrical sleeve with a roughened outer surface for better fixation in the material. The inside of the sleeve is threaded, and the tip is split (expanding), with angled internal walls into which an expansion cone is inserted. The anchor is made of carbon steel, brass, or stainless steel. Stainless fasteners can be used for outdoor installation or operation in aggressive environments.

Anchor installation is carried out in several stages:

• a hole is drilled in the base (concrete or brick slab) with a diameter matching the outer diameter of the anchor sleeve;
• the hole is cleaned of debris, and the anchor is driven in with light force;
• turning the anchor bolt pushes the expansion cone, which spreads the petals at the tip and secures the sleeve inside the material;
• after this, the standard bolt is used to attach external structures or is replaced with another fastening element — a hook, rod, threaded stud, etc.

Applications

The drop-in wedge anchor is easy to install, reliable, and durable. It is used as a base for mounting structures or attaching materials to concrete, brick, or stone bases. This type of anchor should only be installed in solid bases (concrete with a density of at least 200 kgf/cm²). In poor-quality or hollow bases, the anchor may not withstand the weight of the attached structures. For loose or cracked bases, the maximum load capacity of the anchor should be reduced (recommended factor — 0.6).

Drop-in anchors work in shear or tension (pull-out). Under pull-out load, load capacity is provided exclusively by the expanding petals of the sleeve. Therefore, when installing fasteners vertically (for example, into ceiling slabs), the recommendations on embedment depth and anchor load capacity must be strictly followed.
