Wedge anchors are heavy-duty fasteners designed specifically for anchoring items into solid concrete. They are commonly used in structural steel installations, heavy machinery mounting, and highway guardrails.

Drop-in anchors require a pre-drilled hole in solid concrete. Insert the anchor into the hole, then use a setting tool to expand the anchor shield inside the concrete before threading a bolt into it.

Concrete anchors is a broad term that includes all fasteners used in concrete. Expansion anchors are a specific type of concrete anchor that functions by expanding against the sides of a pre-drilled hole when tightened.

Molly anchors are ideal for hollow walls such as drywall, plaster, and hollow tiles. They expand behind the wall surface to provide a secure grip for medium-duty fixtures.

Depending on the material and coating (such as zinc-plated, hot-dip galvanized, or stainless steel), certain anchors are highly resistant to corrosion and suitable for outdoor and harsh environments.
