💡 Why are impact sockets black instead of chrome?
Impact sockets usually get a black finish because they're made from tougher, less brittle steel.

• Impact grade steel flexes a bit under shock instead of cracking
• Chrome sockets are harder and can shatter on an impact wrench
• The black oxide finish helps fight rust in shop and outdoor use
