Hillman Mini Sleeve Anchor 1/2″ x 2‑1/4″ is a steel expansion anchor used to secure fixtures to concrete, brick, hollow block, and other masonry base materials. It works by driving the anchor into a pre‑drilled hole, then tightening the nut, which pulls the screw up and causes the sleeve to expand and grip the base material securely. Made from zinc‑plated steel for durability and moderate corrosion resistance, this type of anchor is ideal for mounting things like shelving, frames, electrical and mechanical attachments, supports, and other fixtures where a strong hold is needed. The 1/2″ diameter and 2‑1/4″ length provide reliable holding power when embedded to the recommended depth, and the hex head (or washer and nut) design makes for straightforward installation with common tools. Because these anchors are versatile and easy to use, they’re popular among both professional contractors and DIYers for light to medium‑duty masonry fastening tasks.
