| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong size wrench, leading to head stripping. | Always use a wrench or socket that precisely matches the 32mm head width of the cap screw. |
| Over-tightening, causing thread damage or material fatigue. | Adhere to the recommended torque specifications for the specific application and materials being joined. |
| Not cleaning mating threads, resulting in galling or improper seating. | Thoroughly clean both the cap screw threads and the receiving threads before installation. |
