Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction.

Regulatory standards & verification citations

  • Total screws = stud count × screws per stud (typically 2 at the top track connection + 2 at the bottom track connection = 4 per stud, per standard CFS framing practice)

Frequently asked questions

Why is the standard default 4 screws per stud?
Standard CFS framing practice fastens each stud to the track with 2 self-tapping screws at the top connection and 2 at the bottom connection, for 4 screws per stud in a typical single-track wall.
Does this count screws for bridging, blocking, or sheathing attachment?
No — this only totals the screws fastening studs to the top and bottom track. Bridging, blocking, strapping, and sheathing/drywall attachment screws must be counted separately.
When would screwsPerStud be higher than 4?
Deeper or heavier-gauge studs, deflection track connections, or project specifications calling for additional screws per connection can raise the count above the standard 4 — check your project's specific CFS framing details.
