California Residential Inspector Practice Exam

What is the minimum center-to-center spacing for screws used in cold-formed steel to steel framing connections?

1. 1/4 inch

2. 1/2 inch

3. 3/4 inch

4. 1 inch

The correct answer is: 1/2 inch

The minimum center-to-center spacing for screws used in cold-formed steel to steel framing connections is specified as 1/2 inch. This spacing is established to ensure sufficient strength and stability in the connection without compromising the structural integrity of the materials involved. In steel construction, particularly with cold-formed steel, proper screw spacing is crucial forload distribution and overall performance of the framing. A 1/2 inch spacing helps to achieve a balance between adequate fastening and avoiding potential issues such as localized shear failure or reduced material integrity. Observing the specified screw spacing contributes to effective load transfer and helps to maintain the durability of the assembly. Understanding this specification is vital for inspectors, as it affects the safety and compliance of framed structures. In construction, adhering to these minimum standards ensures that all connections are robust enough to handle expected loads and resist environmental factors, contributing to the overall longevity of the building.
