| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using a torque wrench set too high, leading to thread stripping or screw breakage. | Consult engineering specifications or a torque chart for the correct torque value for the M17 thread size in 316 stainless steel. |
| Not using a thread lubricant when installing in certain materials, causing galling. | Apply a compatible anti-seize compound or lubricant, especially when fastening into materials prone to galling, to ensure smooth installation and disassembly. |
