The 4 mm form A clevis pin beside the 3 mm and the 5 mm

The 4 mm is number 2, counting from the smallest, of the 5 ISO 2341 clevis pins published here, from 3 mm to 8 mm.

• Shank diameter, nominal (d): 4 mm on the 4 mm form A clevis pin, against 3 mm on the 3 mm and 5 mm on the 5 mm.
• Head diameter, nominal (dk): 6 mm on the 4 mm form A clevis pin, against 5 mm on the 3 mm and 8 mm on the 5 mm.
• Head height, nominal (k): 1 mm on the 4 mm form A clevis pin, against 1 mm on the 3 mm and 1.6 mm on the 5 mm.
• End chamfer length (c): up to 1 mm on the 4 mm form A clevis pin, against up to 1 mm on the 3 mm and up to 2 mm on the 5 mm.
• Head chamfer length (e): 0.5 mm (reference) on the 4 mm form A clevis pin, against 0.5 mm (reference) on the 3 mm and 1 mm (reference) on the 5 mm.
• Underhead radius (r): 0.6 mm on the 4 mm form A clevis pin, the same on the 3 mm and the 5 mm.
• End chamfer angle (c_angle): 30° (reference) on the 4 mm form A clevis pin, the same on the 3 mm and the 5 mm.
• Head chamfer angle (e_angle): 45° (reference) on the 4 mm form A clevis pin, the same on the 3 mm and the 5 mm.
