The 2.5 mm dowel pin beside the 2 mm and the 3 mm

The 2.5 mm is number 2, counting from the smallest, of the 7 ISO 2338 dowel pins published here, from 2 mm to 8 mm.

• Diameter, nominal (d): 2.5 mm on the 2.5 mm dowel pin, against 2 mm on the 2 mm and 3 mm on the 3 mm.
• End chamfer length (c): 0.4 mm (reference) on the 2.5 mm dowel pin, against 0.35 mm (reference) on the 2 mm and 0.5 mm (reference) on the 3 mm.
• End chamfer angle (ch_angle): 15° (reference) on the 2.5 mm dowel pin, the same on the 2 mm and the 3 mm.
