Steel Crank Handles Set Screws

These self-tapping screws with metal hex socket heads and cup points are used to join two or more pieces of material. They are distinguished by their hexagonal head, which can be turned with a hex socket wrench, and their cup-shaped point, which burrows into the material being fastened to prevent the screw from loosening.

The cup point design offers a strong and sturdy attachment by giving a sharp point that bites into the materials. Their self-tapping function removes the need for pre-drilling or tapping, saving time and effort during installation. They have a tensile strength class of 5.8 (500 N/mm2).

A hex socket wrench is required for installation and removal. This is especially useful in applications where screws must be accessible or removed frequently. Used in machine construction, automobile production, and medical device applications.
