#1 × 1/4" براغي صفائح معدنية | رأس دائري | فولاذ (600/عبوة)

Picked up a pack of these for attaching brackets to a metal frame, and the round head sits flush without snagging. The steel feels sturdy enough for the job, and a full 600-count box means I won't run out mid-project.

Used these for mounting a small electrical box to a steel stud, and the round head seated perfectly flush. The steel feels sturdy enough that I don't worry about stripping, and the 600-count box will last me through plenty of projects.

Used these for mounting some light gauge electrical boxes and the #1 size was perfect for the thin metal. The round head sits flush enough for most applications; just wish the steel was a bit more resistant to stripping under high torque.
