The 5 mm spring pin beside the 4.5 mm and the 6 mm

The 5 mm is number 7, counting from the smallest, of the 9 ISO 8752 spring pins published here, from 2 mm to 8 mm.

• Diameter, nominal (d): 5 mm on the 5 mm spring pin, against 4.5 mm on the 4.5 mm and 6 mm on the 6 mm.
• Outside diameter before mounting (d1): 5.4 to 5.6 mm on the 5 mm spring pin, against 4.9 to 5.1 mm on the 4.5 mm and 6.4 to 6.7 mm on the 6 mm.
• Inside diameter before mounting (d2): 3.4 mm (reference) on the 5 mm spring pin, against 2.9 mm (reference) on the 4.5 mm and 4 mm (reference) on the 6 mm.
• End chamfer length (a): 0.9 to 1.1 mm on the 5 mm spring pin, against 0.8 to 1 mm on the 4.5 mm and 1.2 to 1.4 mm on the 6 mm.
• Wall thickness (s): 1 mm on the 5 mm spring pin, against 1 mm on the 4.5 mm and 1.2 mm on the 6 mm.
• Slot width (w): 1.885 mm on the 5 mm spring pin, against 1.885 mm on the 4.5 mm and 2.199 mm on the 6 mm.
• Minimum double shear strength (shear): at least 17.54 mm on the 5 mm spring pin, against at least 15.36 mm on the 4.5 mm and at least 26.04 mm on the 6 mm.
