Metric Thread-Forming Screws for Soft Metal
These screws have a triangular shank that presses tightly as it forms threads, so screws resist loosening in soft metals such as brass, aluminum, and copper. They’re also known as Taptite® screws. Made from steel, they're zinc-plated steel to resist corrosion in wet environments. Length is measured from under the head.
Screws that meet DIN 7500 adhere to international standards for thread-forming screw dimensions. The letter at the end of the standard refers to the screw’s drive type—C for Phillips and D for hex head.
