Carbon steel Hexagon Head Thread Rolling Screws

Name: Metric Thread-Forming Screws for Soft Metal

Material: Carbon steel, Stainless steel SUS304, SUS316

1. 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 Tapping 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. 

2. Stainless Steel Hex Head Thread-Cutting Screws for Metal. Made from 410 stainless steel, these screws are strong, wear-resistant, and mildly chemical-resistant. They have a hex head for a secure grip with a wrench and a flange to reduce the risk of crushing thin metal. Screws 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. Not for use with aluminum. Length is measured from under the flange. Head height includes the flange.
