1. Clean both the screw threads and the mating tapped hole or nut to remove any debris or contaminants. 2. Apply a suitable thread lubricant or anti-seize compound if recommended for the specific application to prevent galling and ensure consistent torque. 3. Insert the screw into the intended fastening point and engage the threads by hand for several turns to prevent cross-threading. 4. Tighten the screw using an appropriate socket wrench or torque wrench to the specified torque value for the M16 size and application requirements.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening the screw, leading to thread stripping or material fatigue. | Always use a calibrated torque wrench and adhere to the recommended torque specifications for the fastener and material being joined. |
| Using a screw of incorrect length or diameter for the application, compromising joint integrity. | Carefully select the correct screw size (M16 x 68mm) and ensure it is appropriate for the combined thickness of the materials being fastened. |
| Failure to properly prepare the mating threads, resulting in difficult installation and potential thread damage. | Thoroughly clean and inspect both the screw and the receiving threads for any damage or foreign material before assembly. |
