The 6 mm external retaining ring beside the 5 mm and the 7 mm

The 6 mm is number 4, counting from the smallest, of the 18 DIN 471 external retaining rings published here, from 3 mm to 20 mm.

• Ring thickness (s): 0.7 mm on the 6 mm external retaining ring, against 0.6 mm on the 5 mm and 0.8 mm on the 7 mm.
• Ring thickness, limits (s_lim): 0.65 to 0.7 mm on the 6 mm external retaining ring, against 0.55 to 0.6 mm on the 5 mm and 0.75 to 0.8 mm on the 7 mm.
• Free diameter (d3): 5.6 mm on the 6 mm external retaining ring, against 4.7 mm on the 5 mm and 6.5 mm on the 7 mm.
• Free diameter, limits (d3_lim): 5.45 to 5.64 mm on the 6 mm external retaining ring, against 4.55 to 4.74 mm on the 5 mm and 6.32 to 6.56 mm on the 7 mm.
• Lug height (a): up to 2.7 mm on the 6 mm external retaining ring, against up to 2.5 mm on the 5 mm and up to 3.1 mm on the 7 mm.
• Radial width (b): 1.3 mm (reference) on the 6 mm external retaining ring, against 1.1 mm (reference) on the 5 mm and 1.4 mm (reference) on the 7 mm.
• Plier hole diameter (d5): at least 1.2 mm on the 6 mm external retaining ring, against at least 1 mm on the 5 mm and at least 1.2 mm on the 7 mm.
• Groove diameter (d2): 5.7 mm on the 6 mm external retaining ring, against 4.8 mm on the 5 mm and 6.7 mm on the 7 mm.
