💡 Why do professional technicians prefer star spline socket sets over standard hex designs?

Shop crews grab these specialized drivers because they spread torque evenly across multiple flat surfaces.

- Exact spline geometry strips less bolt material during aggressive engine teardowns - Handy to keep in dusty garages since the flat contact area prevents camout under pressure - Copper coated bits slide easier on stubborn rusted threads found on older machinery✝️
