Anchor Selection for Concrete and Masonry
Wedge, sleeve, drop-in, ceiling and frame anchors all fix into concrete. They are not interchangeable, and the difference is mostly about what happens after installation.
What You Are Actually Choosing Between
Every mechanical anchor works the same way in principle: a hole is drilled, something expands inside it, and friction against the hole wall carries the load. What separates the types is how the fixture is attached, whether it can be removed, and how much room there is behind the surface.
Wedge Anchors for Permanent Structural Fixings
A wedge anchor is driven through the fixture into the hole and tightened, which pulls a clip up a tapered cone. It is a permanent fixing with a projecting stud, which suits base plates, brackets and equipment bases where nothing needs to come apart later.
Drop-In Anchors Where the Surface Must Stay Flush
A drop-in anchor is set into the hole and expanded with a setting tool before anything is attached, leaving an internally threaded socket flush with the surface. That makes it the choice where the fixture has to be removable, or where a projecting stud would be in the way, which is most services work on soffits.
Sleeve Anchors and What the Head Changes
Sleeve anchors expand a sleeve along most of their length, which spreads the load and makes them more tolerant of variable base material. The head type is the working decision. This range carries sleeve anchors with a hex bolt head, with a flange nut, with an eye bolt for suspended loads and with a hook bolt for hanging services.
Ceiling and Frame Anchors
Ceiling anchors are made for the repetitive overhead work of hanging threaded rod for suspended ceilings and services. Metal frame anchors are made for fixing window and door frames through the frame into the masonry behind, in one operation and without pre-setting a plug.
Buy the Rod and the Nuts With Them
An anchor is half of a fixing. Suspended work needs threaded rod, hex nuts and washers, and buying them from the same supplier as the anchor is what keeps the thread class consistent. The threaded rod in this range is listed by per-piece weight in white zinc and blue zinc.

Questions On This Topic
Which anchor should I use for a suspended ceiling
Ceiling anchors with threaded rod are the usual combination for repetitive overhead hanging work. Drop-in anchors are the alternative where a flush socket is wanted.
Can any of these be removed after installation
A drop-in anchor leaves a threaded socket, so the fixture can be unbolted and refitted. Wedge anchors are permanent.
What finish do the anchors come in
Zinc plating is standard across the range. State the finish on the order so repeat shipments match.
