💡 Why are impact sockets black instead of chrome?
The black finish comes from the tougher steel and coating used on impact sockets.

• Impact grade steel flexes a bit under shock instead of shattering
• A black oxide or phosphate finish helps fight rust
• Chrome plating can chip off under impact hammering
• The dark color makes it easy to tell impact and hand sockets apart
