Metric Painted Steel Pan Head Torx Screws: Add a decorative look when fastening parts—these metric screws have a painted head. Their painted finish is more precise, consistent, and durable than painting the screw yourself—it won't chip or fade. The paint also acts as a barrier, protecting the screw from chemicals and water. To reduce the chance that you'll damage the paint, these screws have a Torx drive. Since this drive has more points of contact than other drive styles, it's harder for the driver to slip while you fasten the screws; if the paint is damaged, these screws are zinc-plated, so they'll still resist corrosion in wet environments. All meet ISO 14583, an international standard for Torx socket screws.
