Buying Guide

Match anchor size to bolt and hole

Choose an anchor diameter and length that corresponds to your bolt size and required embedment depth to ensure proper expansion and load capacity

Select material and plating

Zinc-plated and zinc-alloy anchors resist corrosion for indoor and some outdoor use, while other coatings or stainless options are preferable in high-moisture environments

Consider expansion type

Double-expansion anchors expand at both ends for stronger grip in through-bolt applications, whereas lag shield anchors suit lag bolts and partial embedment uses

Buy by quantity for projects

Anchors are commonly sold in packs (from dozens to hundreds); choose pack size to match project scale and reduce trips for replenishment

Verify masonry compatibility

Confirm the anchor type is rated for the base material—concrete, solid brick, or hollow block can require different anchor designs and installation techniques
