The 8 mm taper pin beside the 6 mm

The 8 mm is the largest of the 7 ISO 2339 taper pins published here, from 2 mm to 8 mm.

• Small-end diameter, nominal (d): 8 mm on the 8 mm taper pin, against 6 mm on the 6 mm.
• End dome length (a): 1 mm (reference) on the 8 mm taper pin, against 0.8 mm (reference) on the 6 mm.
• Taper (1:x) (taper): 50 mm on the 8 mm taper pin, the same on the 6 mm.

Other sizes
