Steel Torx Plus Rounded Head Thread-Forming Screws for Soft Metal

The deep, six-lobe recess keeps drivers from slipping when installing these screws in soft metals such as brass, aluminum, and copper. Torx Plus drives withstand even more torque than Torx. Also known as Taptite® screws, these have a tri-lobular shank that presses threads into material for a tight fit. The unthreaded lead-in point starts threads cleanly and keeps the screw aligned in the hole. Their rounded head creates a finished look.

Length is measured from under the head.

Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.

Black Acrylic-Coated Steel—These screws have a dark coating to create a finished look. They're a common choice for areas with occasional exposure to moisture.

Steel Flanged Hex Head Thread-Forming Screws for Soft Metal

Apply higher torque than other screws can handle when driving into soft metals such as brass, aluminum, and bronze. These screws have a hex head that turns with a nutdriver or socket. Also known as Taptite®, their tri-lobular shank presses threads into material for a tight fit that resists vibration. An unthreaded lead-in point starts threads cleanly and keeps the screw aligned in the hole. The flange under the head spreads the load to prevent crushing thin material.

Length is measured from under the head.
