Hollow Round Boss Design

Notes:

The recommended clearance hole diameter is 1.1D (1.25D is the maximum diameter)
The maximum recommended boss height above the mating surface is 1.5D
Add radius and chamfer to prevent A-surface sink and improve stake strength
These ratios apply to bosses up to 7.62 mm (0.30″) in diameter

Module	Max Height	Max Diameter	Max Through-Hole Size
IS32	12.7 mm (0.500")	9.0 mm (0.354")	9.5 mm (0.374″)
IS125	9.5 mm (0.375")	6.4 mm (0.250")	9.9 mm (0.389″)
ISM20	4 mm (0.157")	4 mm (0.157")	5.5 mm (0.217″)

For dimensions outside of these maximum recommendations, please contact your sales representative or our Process Development Center for feasibility testing.
