| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using a standard hex bolt instead of a cap screw where precise head seating is required. | Ensure the application calls for a cap screw with its accurately machined head for controlled contact and load distribution. Always verify the fastener type specified in the design drawings. |
| Over-tightening or under-tightening the screw, leading to joint failure or component damage. | Utilize a calibrated torque wrench and adhere strictly to the design engineer's specified torque values. Consult engineering documentation for torque recommendations based on material and load requirements. |
