Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong size wrench, leading to head damage or slippage.Always use a 14mm wrench or socket that fits snugly onto the hex head for optimal grip and torque transfer.
Cross-threading the screw due to improper starting or misaligned holes.Start the screw by hand to ensure it threads in easily. If resistance is met, back it out and re-align before continuing.
Over-tightening the screw, which can strip threads or deform the clamped components.Use a calibrated torque wrench and refer to engineering specifications for the correct torque value for your application.
