Q: What is the advantage of a universal impact socket?
A: The universal swivel design allows the socket to flex and access fasteners located at difficult angles or in tight spaces where standard sockets cannot easily reach.
 

Q: Is this socket safe for use with impact tools?
A: Yes — the Sunex 218U is specifically impact rated for use with pneumatic and cordless impact wrenches.
 

Q: Why use a 6-point socket instead of a 12-point?
A: A 6-point socket provides greater surface contact on fastener flats, helping reduce rounding while improving torque transfer during high-load applications.
