Stainless Steel Concrete & Stone Drop-In Female Expansion Anchors – AlbanyCountyFasteners.com – Select Size

If you're anchoring into concrete or stone and need something that won't rust, these stainless steel drop-in anchors are the way to go.

They're female thread expansion anchors, meaning you drop 'em into a pre-drilled hole, set them with a setting tool, and then thread your bolt or rod right in.

They're sold by AlbanyCountyFasteners.com, so you know they're decent quality.

You get to select the size you need—just check the options.

They're brand new, made from stainless steel, and come in original packaging.

No MPN, but for a fastener, that's pretty normal.

Perfect for railings, machinery mounts, or anything that needs a solid hold in masonry.
