| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using incorrect thread pitch for the application, leading to cross-threading. | Verify the thread pitch of the cap screw (M13 standard) matches the tapped hole or nut. |
| Over-tightening the screw, which can strip threads or weaken the material. | Always use a torque wrench and adhere to recommended torque specifications for M13 fasteners. |
| Using a lower-grade stainless steel in corrosive environments, leading to premature failure. | Ensure the use of 316 stainless steel for applications exposed to chlorides, acids, or saltwater. |
