Electrical Grounding Screws
The green color identifies these as grounding screws. They have a flange that provides a wide flat surface for making solid electrical connections. Screws cut threads in drilled holes as they’re turned, so they require less driving torque and cause less stress on your material than thread forming screws. Length is measured from under the flange. Head height includes the flange.
