The 8 mm spring pin beside the 6 mm

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

• Diameter, nominal (d): 8 mm on the 8 mm spring pin, against 6 mm on the 6 mm.
• Outside diameter before mounting (d1): 8.5 to 8.8 mm on the 8 mm spring pin, against 6.4 to 6.7 mm on the 6 mm.
• Inside diameter before mounting (d2): 5.5 mm (reference) on the 8 mm spring pin, against 4 mm (reference) on the 6 mm.
• End chamfer length (a): 1.6 to 2 mm on the 8 mm spring pin, against 1.2 to 1.4 mm on the 6 mm.
• Wall thickness (s): 1.5 mm on the 8 mm spring pin, against 1.2 mm on the 6 mm.
• Slot width (w): 2.513 mm on the 8 mm spring pin, against 2.199 mm on the 6 mm.
• Minimum double shear strength (shear): at least 42.76 mm on the 8 mm spring pin, against at least 26.04 mm on the 6 mm.
