Which anchor is used for lightweight mounting such as smoke detectors?

• A. Nail
• B. Light
• C. Drop-in
• D. Lag

Answer: (B)

Choosing the right anchor depends on how much weight you’re supporting and what material you’re going into. For lightweight mounting like smoke detectors, a light-duty anchor is the best choice. These anchors are designed to grip drywall or plaster and hold a screw securely without needing a stud behind the surface. They spread the load over a small area so the screw doesn’t pull out easily, making installation quick and reliable for small, not-too-heavy fixtures. Nails aren’t anchors, so they don’t provide a secure hold for mounting devices on drywall. Drop-in anchors are meant for concrete or masonry and handle much heavier loads, while lag screws are intended for wood and stud framing. Using those in drywall would be overkill or simply ineffective. So, for a lightweight item such as a smoke detector mounted on drywall, a light-duty drywall anchor is the appropriate choice.
