Hillman 370826 Hex Head Sleeve Anchor – 5/16” X 2-1/2”, Zinc-Plated, 35-Pack For Concrete, Brick & Block – Ideal For Fixtures, Frames & Shelving

About This Product

If you need to fasten something solidly into concrete, brick, or block, these sleeve anchors are a go-to choice.
Each one is 5/16 inch in diameter and 2-1/2 inches long, with a hex head that you tighten with a wrench.

As you turn the nut, the working end expands inside the hole, locking the anchor securely in place.

They’re zinc-plated, which gives them decent corrosion resistance for indoor or sheltered outdoor use.
This 35-pack gives you plenty for a project—think door and window frames, shelving, storage racks, electrical boxes, or any other heavy fixture that needs a reliable hold.

Just remember to pre-drill the right size hole (the package specs tell you what bit to use).

Simple, strong, and widely used by pros and DIYers alike.

Keep a pack in your workshop and you’ll be ready for the next mounting job.
