The use of No. 8 screws for fastening steel reinforcing in the framing process is based on their balance of strength and size, making them an appropriate choice for securing metal components. No. 8 screws typically have a sufficient diameter and length to securely anchor into the material without risking damage, ensuring robust fastening in steel framing applications.

In construction, specifically when dealing with steel or other metals, it's important to choose a screw that can adequately handle the load and any potential stressors on the joint. No. 8 screws strike a good balance between being versatile and providing adequate holding power for lighter steel applications. They are commonly used in various applications where a strong joint is required without the need for larger, heavier screws that could be excessive or impractical.

Screw sizes such as No. 6, No. 10, and No. 12 may either not provide as much grip or may be too large for some applications, potentially causing damage to the steel components being fastened. Thus, No. 8 screws are generally favored for their appropriateness in typical framing tasks involving steel reinforcement.
