Brick anchor fasteners attach an item to bricks or mortar joints in a brick wall. Brick anchors are used in place of concrete fasteners because brick contains hollow spaces, unlike concrete that is solid. The hollow space requires a brick anchor in order to obtain the needed holding values in the hollow areas.
They may be small, but masonry anchors play a mighty—and vital—role in securing fixtures, structural elements, decorations, and equipment to brick walls. Finding the right fixture can prevent a potential catastrophe in your home.
Yes always use a plug if it's going into brick.
Sleeve anchors work well in brick. Wedge anchors don't work very well as the brick is too soft. Sometimes Tapcons will work. It depends on the brick and with Tapcons you need to get the exact diameter hole which can be slightly different for different density materials.
Drywall anchors aren't required for all wall-based fastening applications. If there's a stud directly behind the wall, for instance, you probably won't need to use them. Studs offer support for screws as well as the objects with which they are used. Of course, studs don't encompass the entire space of a given wall.
If there's a stud located where you want to hang your item, you might be able to avoid installing a drywall anchor—the wood will provide the appropriate resistance and keep your item in place. If you can't find a stud, you'll have to weigh the item at hand to find out which type of drywall anchor will work best.
Anchor Types Overview
Masonry and concrete anchor types are considered light-duty, medium-duty or heavy-duty, based on how much weight they can support. Light-duty anchors are good for wall hangings that weigh up to 50 pounds. Medium-duty anchors are good for wall hangings that weigh up to 200 pounds.
Wedge anchors are one of the strongest anchors available. They come in nine different diameters and several different lengths. The larger the anchor, the more holding power it has. They also come in several different materials, so you can use them in areas with or without the possibility of corrosion.
Brick and Masonry
These fasteners are designed to attach items to bricks or mortar joints in walls, providing a secure anchoring solution. As brick contains hollow areas, masonry anchors for brick are specially designed to provide a secure hold in both the solid and hollow parts of the brick wall.
FIX plugs – the right type of plug for solid surfaces, where they perform best. An engineered surface and a two-way expansion mechanism, giving it excellent performance in concrete and solid brick. The anti-rotation fins prevent spinning during tightening of the screw.
As a general rule, always drill into the brick unless you're hanging something very light (under two pounds). Mortar is much softer than brick and doesn't have the strength to hold significant weight. Mortar deteriorates faster than brick, which could compromise the stability of your installation over time.
Wall plugs are required for hollow walls like plasterboard, and solid walls such as brick or concrete. In general, screws can be inserted directly into wood without the use of plugs.
A drop-in anchor is designed for solid concrete, while a machine screw anchor is designed for use in brick, block, and concrete.
Use a hammer to carefully tap the anchor into the hole until the collar of the anchor is flush with the wall surface. Don't drive the collar beneath the surface of the wall. For some types you may need to fold down the flanges to install the anchor.

Brick anchors are used in place of concrete fasteners because brick contains hollow spaces, unlike concrete that is solid. The hollow space requires a brick anchor in order to obtain the needed holding values in the hollow areas.
Zinc plated sleeve anchors should be used in indoor dry areas, stainless steel sleeve anchors should be considered for use in outside applications. All sleeve anchors come pre-assembled and ready to use. The hole that is required to be drilled into the brick is the same diameter as the sleeve anchor being used.
Threaded drywall anchors are suitable for objects weighing up to 25 pounds and are ideal for use on drywall. Hollow-wall anchors can hold up to 30 pounds per pair on plaster, paneling and other hollow walls.
A single 4mm diameter screw into a 30x6mm Fischer Duopower wall plug in a solid brick will support 50kg - and this is the smallest plug I routinely use. You have to be more wary if you have plasterboard - which can be fixed to studs (wood or metal) or it can be stuck on solid walls (dot & dab) with a small void.
Anchors and Plugs
Anchors expand within the wall, providing a secure hold. Wall plugs are inserted into pre-drilled holes and create a stable base for screws. Common types include plastic plugs, metal anchors, and chemical anchors. Ensure you choose the appropriate size and type of anchor/plug for your wall material.
Wall anchors are a MUST when it's not possible to hit a stud when hanging items on walls. Nails and screws can easily slip out or cause the wall to break apart if an anchor isn't used, and picking the right type and installing them correctly are crucial.
Use studs for heavy-duty hanging
You definitely want to hit a stud for heavy-duty loads like a TV bracket, a handrail, or a grab bar. Hollow wall anchors won't cut it. And for that, you first need to find the studs.
How it works: A molly bolt is a screw encased with metal that expands in a predrilled hole to support medium-weight items. Best for: high-use and mid-weight range items, like coat hooks, or with lightweight items in the ceiling, such as smoke detectors. Weight limit: 25 to 50 pounds.
