In the world of industrial fasteners, precision and reliability are not just goals—they are absolute necessities. Japan’s industrial standards have long set a benchmark for quality in engineering, and among them, plays a specific and vital role. While the standard is widely recognized, there is also significant confusion surrounding it, particularly its relationship with modern screw head designs like Torx.
The standard includes detailed tables for thread sizes from M2 up to M8, covering head diameter (dk), head height (k), cross-recess dimensions, various washer dimensions (D1, t), and the important 'a' dimension—the length of the unthreaded shank from the washer to the start of full threads.
