Metric self tapping screw belongs to kind of self-tapping screws, but it is different from ordinary self-tapping screws, it belongs to special type of screws.
Metric self tapping screw adopts the most advanced cold heading production process, which ensures that the head of the screws is well formed and the quality of the threads is very high.
For present, high-speed cold heading machines and high-speed thread rolling machines or high-speed planetary thread rolling machines are usually used to produce this product at home and abroad.
Metric self tapping screw is available in excellent strength grades, such as Grade 8.8, 10.9 and other strength grades, with higher tensile and yield strengths. This means they can withstand greater loads and more complex stress environments, meeting a variety of high-performance requirements.
The size range of Metric self tapping screw covers a very wide range. From the smallest 0-80 thread to the largest 1-8 thread, American screws cover a common and universal size range.
