The 10 mm internal retaining ring beside the 9 mm and the 11 mm

The 10 mm is number 3, counting from the smallest, of the 17 DIN 472 internal retaining rings published here, from 8 mm to 25 mm.

• Ring thickness (s): 1 mm on the 10 mm internal retaining ring, against 0.8 mm on the 9 mm and 1 mm on the 11 mm.
• Ring thickness, limits (s_lim): 0.94 to 1 mm on the 10 mm internal retaining ring, against 0.75 to 0.8 mm on the 9 mm and 0.94 to 1 mm on the 11 mm.
• Free diameter (d3): 10.8 mm on the 10 mm internal retaining ring, against 9.8 mm on the 9 mm and 11.8 mm on the 11 mm.
• Free diameter, limits (d3_lim): 10.7 to 11.16 mm on the 10 mm internal retaining ring, against 9.7 to 10.16 mm on the 9 mm and 11.7 to 12.16 mm on the 11 mm.
• Lug height (a): up to 3.2 mm on the 10 mm internal retaining ring, against up to 2.5 mm on the 9 mm and up to 3.3 mm on the 11 mm.
• Radial width (b): 1.4 mm (reference) on the 10 mm internal retaining ring, against 1.3 mm (reference) on the 9 mm and 1.5 mm (reference) on the 11 mm.
• Plier hole diameter (d5): at least 1.2 mm on the 10 mm internal retaining ring, against at least 1 mm on the 9 mm and at least 1.2 mm on the 11 mm.
• Groove diameter (d2): 10.4 mm on the 10 mm internal retaining ring, against 9.4 mm on the 9 mm and 11.4 mm on the 11 mm.
