| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong size wrench, leading to damaged fastener heads or improper torque. | Always use a wrench or socket that precisely matches the 16mm head width of the cap screw for optimal grip and torque transfer. |
| Over-tightening the fastener, which can strip threads or lead to material fatigue. | Utilize a torque wrench and adhere to the recommended torque specifications for the M23 thread size and material grade to prevent damage. |
