Concrete Anchors: Types, Sizing & Installation

Concrete anchors come in more types than most people realize — wedge anchors, sleeve anchors, drop-in anchors, Tapcon screws, toggle/hollow-wall anchors, and more — each rated for different loads and substrates. Picking the wrong one (or drilling the wrong hole size) is the most common reason anchors fail. Below you'll find guides on every anchor type, how to choose between them, load capacities, spacing and edge distance rules, and step-by-step installation.

Start with types of concrete anchors explained or our anchor selection chart to find the right category for your project. From there, load capacity and spacing & edge distance determine exactly where and how many anchors you need, and our installation guide covers the drilling and setting process step by step. If you're comparing options for a specific project, see Tapcon screws vs. concrete anchor bolts and our best concrete anchors for home use roundup. For the engineering behind all of it, see ACI 318-19 explained, embedment depth, and how to read an anchor ESR report.
