For a small outdoor light bracket, the best anchor depends less on the light’s weight than on what the screws will bite into: solid brick, hollow brick, or the mortar joint. First identify the material and check the bracket’s hole size. A strong anchor in the wrong substrate can still pull out—or crack the masonry.

What we cover
Identify the masonry before buying
Brick is not always solid. Tap the spot and inspect an exposed edge if possible, but don’t rely on sound alone. A small pilot hole in an inconspicuous spot can reveal whether you hit solid material or a cavity. Stop if the brick crumbles or splits; move the bracket rather than trying to rescue weak masonry with a larger screw.
Whenever the layout permits, put the fasteners into the brick, not the mortar. Mortar is generally softer and can deteriorate outdoors. If a joint is the only practical location, use an anchor intended for masonry and make sure the mortar is sound. Avoid drilling near brick edges: keep holes at least about 1½ inches from an edge where the bracket allows it, and follow the anchor maker’s larger clearance requirement if specified.
Anchor options at a glance
| Anchor type | Best fit | Advantages | Common failure |
|---|---|---|---|
| Plastic masonry plug | Solid, sound brick; light bracket | Inexpensive and simple to install | Spins or pulls out in a loose, oversized hole |
| Concrete screw | Solid brick; repeatable, firm fastening | Direct installation and strong holding when correctly drilled | Strips the hole if driven too hard or into crumbly brick |
| Toggle-style hollow-wall anchor | Hollow brick, if the anchor is rated for that substrate | Can bear behind a cavity | Cannot deploy properly in a narrow or blocked void |
| Epoxy or bonded threaded rod | Special cases or a specified anchoring system | Can work in suitable masonry when installed to instructions | Poor results from dirty holes, wrong adhesive, or inadequate cure time |
What to buy for a small light
For a modest bracket on solid brick, a correctly sized nylon masonry plug set is often the economical choice. It is suitable when the fixture is light, the brick is sound, and the anchor package gives a load rating for masonry. Match the plug and screw sizes exactly; a random screw can split the plug or fail to expand it.
For a firmer hold, consider masonry concrete screws. These cut threads into a properly sized pilot hole and avoid a separate plastic plug. They are not foolproof: an oversized or dusty hole can leave the screw loose, while excessive torque can strip the threads in the brick. Check the screw manufacturer’s instructions for the required bit diameter, embedment, and edge spacing.
Do not choose by a headline load figure alone. Ratings vary with brick type, hole quality, spacing, and whether the load pulls straight out or hangs down. A light fixture also sees wind and vibration. Use the number and size of fasteners the bracket was designed for, and do not assume one anchor can safely carry the whole fixture.
Drill the hole without damaging the brick
Use a masonry bit of the exact diameter specified for the anchor. A hammer drill with a masonry bit makes quick work of solid brick, but hammer action can chip brittle brick or damage a weak edge. For a small hole in fragile masonry, start with rotation only. If the bit struggles, switch to hammer mode with light pressure. A regular drill can work for a small hole, though it will be slower.
Mark the hole through the bracket, then remove the bracket before drilling. Keep the drill square to the surface and use a depth stop or tape mark. Drill only as deep as the anchor requires; a hole that is too shallow prevents full seating, and one that is too deep can let a plug disappear into the wall. Brush or blow masonry dust out of the hole as the anchor instructions direct. Dust left behind can reduce grip, especially with screws or bonded anchors.
Seat the anchor without hammering it so hard that the brick face spalls. Tighten the screw until the bracket is secure, then stop. If the anchor spins, the hole is probably oversized or the surrounding brick is weak. Do not compensate by forcing in a larger screw unless the anchor manufacturer explicitly allows it; relocate the fastener or choose a suitable repair method.
Hollow brick and outdoor details
In hollow brick, a standard plug may expand into a thin shell and crack it. A cavity anchor can be a better match, but only if its design and rating cover hollow masonry and there is enough open space behind the shell. For this situation, a hollow-brick anchor assortment is useful only when the package identifies the substrate and installation method. If the bracket is over a cavity or the brick is damaged, get advice from the fixture or anchor manufacturer rather than guessing.
Use corrosion-resistant screws and anchors suited to the outdoor environment; stainless steel or appropriately coated hardware helps limit rust streaks and seized fasteners. Keep the fixture’s wiring and any sealing requirements separate from the anchor decision: seal the wall penetration as the light manufacturer directs, without trapping water behind the bracket. Test that the installed bracket does not rock before mounting the light.
