What is the maximum recommended spacing between drywall screws when attaching 1/2-inch drywall to wood studs?
Correct Answer
B) 12 inches on center
The maximum recommended spacing for drywall screws when attaching to wood studs is 12 inches on center to ensure proper attachment and prevent sagging or cracking.
Why This Is the Correct Answer
The maximum recommended spacing for drywall screws when attaching 1/2-inch drywall to wood studs is 12 inches on center according to industry standards and building codes. This spacing ensures adequate holding power to prevent the drywall from sagging under its own weight or developing cracks at the joints. Closer spacing provides better support but is not required, while wider spacing would compromise the structural integrity of the installation.
Why the Other Options Are Wrong
Option A: 8 inches on center
8 inches on center is closer than required and would be considered conservative but not the maximum allowable spacing
Option D: 16 inches on center
16 inches on center exceeds the maximum recommended spacing and could result in inadequate support, leading to sagging drywall and potential cracking
Memory Technique
Think '12 for drywall' - the same number as inches in a foot makes it easy to remember the maximum screw spacing
Reference Hint
Check the Gypsum Association's GA-216 standard or the International Building Code Chapter 25 for interior wall finish requirements
