The 2 mm spring pin beside the 2.5 mm

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

• Diameter, nominal (d): 2 mm on the 2 mm spring pin, against 2.5 mm on the 2.5 mm.
• Outside diameter before mounting (d1): 2.3 to 2.4 mm on the 2 mm spring pin, against 2.8 to 2.9 mm on the 2.5 mm.
• Inside diameter before mounting (d2): 1.5 mm (reference) on the 2 mm spring pin, against 1.8 mm (reference) on the 2.5 mm.
• End chamfer length (a): 0.35 to 0.55 mm on the 2 mm spring pin, against 0.4 to 0.6 mm on the 2.5 mm.
• Wall thickness (s): 0.4 mm on the 2 mm spring pin, against 0.5 mm on the 2.5 mm.
• Slot width (w): 1.257 mm on the 2 mm spring pin, the same on the 2.5 mm.
• Minimum double shear strength (shear): at least 2.82 mm on the 2 mm spring pin, against at least 4.38 mm on the 2.5 mm.
