Steel Hex Head Drilling Screws for Metal
Zinc-Plated Steel External Hex/Slotted
These steel screws have corrosion-resistant finishes. A hex head provides a secure grip with a wrench and a flange reduces the risk of crushing thin metal. They save you time and effort by drilling their own holes and fastening in a single operation. Length is measured from under the flange. Head height includes the flange.
Zinc-plated steel screws resist corrosion in wet environments.
