What is the minimum number of fasteners required for attaching a steel floor joist to the track of an interior load-bearing wall?

The minimum number of fasteners required for attaching a steel floor joist to the track of an interior load-bearing wall is based on industry standards and building codes that ensure structural integrity. Specifically, two #8 screws are typically sufficient to adequately secure the connection between the joist and the track, as they provide a good balance between strength and accessibility.

Using two screws allows for effective load distribution and anchoring of the joist while keeping fastening work streamlined and efficient. This is essential in maintaining the structural consistency of the wall and floor system without excessive use of materials, which might not be necessary for sufficient strength. In load-bearing applications, ensuring each connection is solid is critical, and two well-placed screws can accomplish that effectively.

Other options may suggest a higher number of screws, reflecting either an unnecessary redundancy or misinterpretation of the minimum requirements stated in codes or guidelines. These alternatives may overestimate the needs for fastening in this particular scenario. Thus, choosing two #8 screws aligns with standard practices for securing steel joists in these applications.
