Milwaukee Spark Plug Sockets Milwaukee spark plug sockets feature durable dual-material rubber retainers designed to maintain a more secure fit within the socket while securely holding onto spark plugs to avoid dropping or damaging. A precision knurling on the outside of the socket allows for better control when hand tightening or loosening， and both the socket and retainer can withstand harsh chemicals commonly found in the garage. Milwaukee 6-point spark plug sockets are chrome plated steel construction and stamped with size markings， making it easy to identify the size of the socket. A wrench can be used on the external hex at the base of the socket for added control. Milwaukee sockets are offered in several sizes and backed with a Lifetime Guarantee. Choose the preferred sizes to add to your tool arsenal.
