Which size screws are required for mounting light fixtures?

• A. No. 6-32
• B. No. 8-32
• C. No. 10-32
• D. No. 12-32

Answer: (B)

To mount light fixtures, the appropriate screw size is critical for ensuring secure installation. No. 8-32 screws are commonly used in electrical installations for this purpose because they provide a good balance of strength and compatibility with typical fixture mounting brackets. The "8" indicates the screw diameter, and "32" refers to the threads per inch, which is standard for many applications in electrical work.

Using No. 8 screws helps ensure that the fixtures are held firmly in place, allowing for effective weight distribution and stability, which is especially important for ceiling-mounted fixtures that may carry significant weight or endure vibrations over time. This size is compatible with most mounting hardware specified by fixture manufacturers, making it the industry standard for such installations.
