Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using a socket that is too large or too small for the hex head.Always use a properly sized socket that fully engages all six flats of the hex head to prevent cam-out and fastener damage.
Applying excessive torque, leading to thread stripping or fastener fracture.Consult torque charts for the specific grade of carbon steel and application to ensure proper tightening and prevent overstressing the fastener.
