The 12 mm E-clip beside the 10 mm and the 15 mm

The 12 mm is number 10, counting from the smallest, of the 11 DIN 6799 E-clips published here, from 2.3 mm to 15 mm.

• Clip thickness (s): 1.3 mm on the 12 mm E-clip, against 1.2 mm on the 10 mm and 1.5 mm on the 15 mm.
• Clip thickness, limits (s_lim): 1.27 to 1.33 mm on the 12 mm E-clip, against 1.17 to 1.23 mm on the 10 mm and 1.47 to 1.53 mm on the 15 mm.
• Mouth width (a): 10.45 mm on the 12 mm E-clip, against 8.32 mm on the 10 mm and 12.61 mm on the 15 mm.
• Mouth width, limits (a_lim): 10.38 to 10.52 mm on the 12 mm E-clip, against 8.262 to 8.378 mm on the 10 mm and 12.54 to 12.68 mm on the 15 mm.
• Outer diameter, installed (d3): up to 23.4 mm on the 12 mm E-clip, against up to 20.4 mm on the 10 mm and up to 29.4 mm on the 15 mm.
• Groove diameter (d2): 12 mm on the 12 mm E-clip, against 10 mm on the 10 mm and 15 mm on the 15 mm.
• Shaft diameter range (d1): 13 to 18 mm on the 12 mm E-clip, against 11 to 15 mm on the 10 mm and 16 to 24 mm on the 15 mm.
• Groove width (m): 1.35 mm on the 12 mm E-clip, against 1.25 mm on the 10 mm and 1.55 mm on the 15 mm.
