1. Ensure mating threads are clean and free from debris. 2. Apply a small amount of appropriate lubricant to the threads if necessary for smoother engagement and to prevent galling. 3. Insert the cap screw and engage threads by hand to prevent cross-threading. 4. Tighten using a suitable wrench or socket to the recommended torque specification for the application and materials being joined.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Cross-threading the screw during installation. | Always start engaging the threads by hand to confirm alignment before applying any torque. |
| Over-tightening the screw, which can strip the threads or damage the mating material. | Utilize a torque wrench and adhere to the specified torque values for the application. Brass is a softer material and requires careful torque management. |
| Using the wrong size wrench or socket, leading to damaged hex head. | Ensure the wrench or socket perfectly matches the 24mm head width to avoid stripping or deformation. |
