Drop-In Anchors

Drop-In Anchors

Drop-in anchors are specifically designed for use with concrete. The anchor consists of two components: the anchor body and the expander plug. When the drop-in anchor is installed in a concrete product or structure, the plug forces the anchor to expand inside the hole. Friction holds the anchor permanently in place. The strength of the drop-in anchor depends on several factors including its size, the depth of the hole that drilled to accommodate the anchor and the strength of the concrete.

Examples of the numerous drop-in-anchor applications include the installation of handrails, shelves, overhead hangers, machinery and lighting fixtures.

How Do You Install Drop-In Anchors?

The drop-in anchor installation process consists of five simple steps:

  • Step one: Drill a hole in the concrete that is slightly larger than the diameter of the anchor to allow the anchor necessary expansion room.
  • Step two: Remove all debris from inside the drilled hole.
  • Step three: Drop the slotted end of the anchor into the hole.
  • Step four: Insert a setting tool into the hole and strike it with a hammer until its lip is aligned with the anchor’s top.
  • Step five: Set the fixture over the anchor and insert the machine-threaded bolt or threaded rod into the fixture.

It isn’t necessary to use an epoxy or other adhesive material to hold an installed drop-in anchor in place.

Drop-In Anchor vs. Wedge Anchor

Drop-in anchors are sometimes confused with wedge anchors. While they both work the same way — they expand and fill the inside of a hole in concrete — the wedge anchor features a conical-shaped hollow bottom. Wedge anchors are usually the better option for applications involving heavy bearing loads.
