| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using incorrect thread pitch for the application. | Verify the thread pitch of the cap screw matches the receiving thread (nut or tapped hole) to prevent cross-threading and ensure secure fastening. |
| Over-tightening, leading to thread stripping or material deformation. | Adhere to specified torque values, especially in critical assemblies. Use a torque wrench to prevent overstressing the fastener and the mating components. |
