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

The 3 mm is number 3, counting from the smallest, of the 7 ISO 2338 dowel pins published here, from 2 mm to 8 mm.

• Diameter, nominal (d): 3 mm on the 3 mm dowel pin, against 2.5 mm on the 2.5 mm and 4 mm on the 4 mm.
• End chamfer length (c): 0.5 mm (reference) on the 3 mm dowel pin, against 0.4 mm (reference) on the 2.5 mm and 0.63 mm (reference) on the 4 mm.
• End chamfer angle (ch_angle): 15° (reference) on the 3 mm dowel pin, the same on the 2.5 mm and the 4 mm.

Other sizes

• One size smaller: 2.5 mm Dowel Pin (Parallel Pin), ISO 2338.
• One size larger: 4 mm Dowel Pin (Parallel Pin), ISO 2338.
