InfraStake Design Guidelines
Download these guidelines.
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″) |
