What type of duty are stud anchors classified as?

• A. Light duty
• B. Medium duty
• C. Heavy duty
• D. Extra heavy duty

Answer: (B)

Stud anchors are designed to handle a moderate level of load, enough for typical wall-framing and interior fastening tasks without requiring oversized, heavy-duty hardware. That’s why medium duty fits best: it offers sufficient pullout and shear strength for everyday applications like securing metal studs, furring, or light fixtures to masonry or concrete, while staying compact and easier to install than heavy or extra-heavy options. Light-duty would not provide enough strength for common stud installations, and heavy or extra-heavy duty would be unnecessarily strong and harder to install for these uses.
