Milwaukee Tool 48-22-9552 Spark Plug Socket 5/8 in

Product Description

The MILWAUKEE TOOL 48-22-9552 is a 5/8-inch spark plug socket designed for removing and installing spark plugs in gasoline engines. It accepts a 3/8-inch square drive and features a 6-point contact geometry that reduces the chance of rounding fasteners under high torque. The socket includes a magnetic retention feature to hold the spark plug during extraction and installation, reducing the risk of dropping hardware in tight engine bays. Built from steel with a stainless steel coating, it measures 2.68 inches in overall length and weighs 0.225 pounds. MILWAUKEE TOOL backs this socket with a lifetime warranty. It is suited for automotive technicians, small-engine mechanics, and experienced DIYers performing tune-up work.

This spark plug socket is sized for standard 5/8-inch spark plugs commonly found in passenger vehicles, light trucks, and small-engine equipment. The standard-length profile works in most open engine bays where spark plugs are accessible without deep-reach clearance. It is sold individually and is a practical addition to a service technician's socket set when a dedicated spark plug socket is needed for routine ignition maintenance.

Key Features

• 5/8-inch socket size for standard spark plug hex engagement
• 3/8-inch square drive for compatibility with common ratchets and extensions
• 6-point design reduces fastener rounding during high-torque removal
• Magnetic retention holds spark plug securely during removal and installation

Compatibility

Designed as an OEM-style replacement and service socket for use with standard 5/8-inch spark plugs on gasoline engines requiring a 3/8-inch drive tool.

Installation Notes

This socket is installed and removed by automotive or small-engine technicians using a 3/8-inch drive ratchet or torque wrench. Disconnect the ignition coil or spark plug wire and allow the engine to cool before service. Use an extension bar if plug access requires additional reach. Do not use impact drivers with this hand socket unless the socket is explicitly rated for impact use.
