The 3 mm taper pin beside the 2.5 mm and the 4 mm

The 3 mm is number 3, counting from the smallest, of the 7 ISO 2339 taper pins published here, from 2 mm to 8 mm.

• Small-end diameter, nominal (d): 3 mm on the 3 mm taper pin, against 2.5 mm on the 2.5 mm and 4 mm on the 4 mm.
• End dome length (a): 0.4 mm (reference) on the 3 mm taper pin, against 0.3 mm (reference) on the 2.5 mm and 0.5 mm (reference) on the 4 mm.
• Taper (1:x) (taper): 50 mm on the 3 mm taper pin, the same on the 2.5 mm and the 4 mm.

Other sizes

• One size smaller: 2.5 mm Taper Pin (Tapered Pin), ISO 2339.
• One size larger: 4 mm Taper Pin (Tapered Pin), ISO 2339.
