84603MB 3-Piece Super Thin Wall Impact Socket Set |- ½”Drive

Why are there plastic sleeves on these impact sockets? The PVC sleeves on the 84603MB are designed to protect expensive alloy wheels. When you are using an impact wrench, the socket spins very fast; the plastic sleeve acts as a barrier so the metal socket doesn’t scratch the paint or finish of the wheel rim.

Can I use these for other engine repairs? While you can, these are specifically engineered for Wheel Lug Nuts. Because they are “Super Thin Wall,” they prioritize clearance. For general high-torque engine repair where clearance isn’t an issue, we recommend using our standard 84400M series sockets for maximum structural thickness.

Are these sockets strong enough for pneumatic impact guns? Yes. Every socket in the 84603MB set is forged from Chrome Molybdenum (Cr-Mo) steel. This is a heavy-duty, impact-rated alloy that is designed to flex slightly under the stress of an impact gun instead of shattering like a regular hand tool
