Extra-Wide Rounded Head Drilling Screws for Metal
The extra-wide truss head distributes holding pressure to reduce the risk of crushing thin metal. Use these screws to secure metal wire to steel framing. They save you time and effort by drilling their own holes and fastening in a single operation. Made from steel, they have a zinc plating to resist corrosion in wet environments. Length is measured from under the flange. Head height includes the flange.
