Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the screw, which can lead to thread stripping or material fatigue.Always use a torque wrench and consult material-specific torque charts for accurate tightening.
Using incompatible tools, potentially damaging the hex head or the tool.Utilize a high-quality hex wrench or socket that precisely matches the head dimensions.
Not cleaning the mating threads before installation, leading to increased friction and inaccurate torque readings.Thoroughly clean both the screw and the receiving threads prior to assembly.
