💡 What's the difference between 6-point and 12-point sockets?
Point count changes how the socket grabs a nut or bolt head.

• 6-point sockets grip the flat sides for max torque and less rounding
• 12-point sockets are easier to slip on when swing room is tight
• Go 6-point for rusty, stubborn, or high-torque fasteners
• 12-point is handy for double-hex bolts on some engines and machines
