Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong size wrench, leading to stripped screw heads.Always use a wrench or socket that precisely fits the 10mm hex head for optimal torque transfer and to prevent damage.
Over-tightening the screw, potentially damaging the threads or the mating material.Tighten to the recommended torque for the application. For critical joints, use a torque wrench.
Using stainless steel fasteners in environments prone to galling without proper lubrication.Apply a small amount of anti-seize compound specifically designed for stainless steel to prevent galling during installation.
