Steel Rounded Head Thread-Cutting Screws for Metal
These steel screws are zinc plated to resist corrosion in wet environments. They 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 head.
Screws meet ASME B18.6.3 dimensional standards. They also meet SAE J933 for material quality.
