| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using an undersized or oversized tool, leading to stripped head or inadequate torque. | Always use a hex wrench or socket that precisely fits the 15mm head width for optimal force transfer and fastener integrity. |
| Cross-threading the screw, resulting in damaged threads and a compromised joint. | Carefully align the screw with the mating thread and initiate tightening by hand for several turns before using a tool. |
