１. Screw Grade
※For stainless steel screws, classified as standard "T" grade, like the yellow frame.
２. Thread Width
If the width is 10mm, it is designated as 『M10』
３. Confirming Torque
『M10 + T grade』corresponds to『24.5 Nm』, like the yellow frame.
※ 1 Nm = 10.2 kgf-cm = 0.738 lbf-ft = 8.851 lbf-in
