I have a job coming up that will require 12 gauge metal studs. When ever we have used them in the past it was limited so we just used heavy duty self tappers, usually 1/4 head tek-5s. This job coming up is a lot of studs so i'm wondering if there is a better more efficient way to fasten them to the track. Like spot welding or tacking them with an arc welder or something? Has anyone tried anything different?
