Crescent CSPS4N 1/2" Drive 6-Point 13/16" Magnetic Swivel Spark Plug Socket

The Crescent CSPS4N 1/2-inch drive 13/16-inch magnetic swivel spark plug socket extracts and installs engine spark plugs in recessed cylinder heads without dropping hardware. Engineered from heat-treated chrome vanadium alloy steel with an articulating universal swivel joint and off-corner Surface Drive technology that prevents fastener rounding, this 6-point hand tool provides smooth access to obstructed engine bays. Outfitted with an integrated magnetic core to retain spark plugs securely and a full-polish nickel-chrome finish that resists shop corrosion, it equips automotive technicians, small-engine specialists, and service pros with dependable, ASME-compliant tune-up performance.

Best Used For:

  • Automotive and Truck Engine Tune-Ups: Removing and torqueing 13/16-inch hex spark plugs in deep, recessed aluminum cylinder heads without dropping the plug into the engine bay.
  • Confined Engine Bay and Firewall Servicing: Navigating around brake boosters, intake manifolds, and strut towers using the flexible 360-degree articulating swivel joint.
  • Small Engine and Marine Equipment Maintenance: Servicing lawnmowers, generators, commercial tractors, and marine outboard engines in tight compartments.

Key Performance & Safety Features

  • Integrated Magnetic Core: Powerful interior magnet holds the spark plug firmly during extraction and installation, preventing drops and broken porcelain insulators.
  • Articulating Swivel Head: Smooth pivoting joint allows ratchets and extensions to work at off-axis angles in crowded engine bays.
  • Surface Drive Technology: Off-corner loading profile grips fastener flats rather than corners to eliminate spark plug stripping and hex rounding.
  • Heat-Treated Chrome Vanadium Steel: Forged alloy steel body provides high structural strength and impact fatigue resistance under heavy hand torque.
  • Full-Polish Nickel Chrome Finish: Mirror-polished plating repels motor oils, grease, and shop solvents while wiping clean easily.
  • ASME B107.34 Compliance: Precision-manufactured to meet or exceed rigorous industrial standards for socket dimensions and torque performance.

Pro-Tip: When installing a new spark plug, always start threading it into the cylinder head by hand using only the socket and an extension; avoid attaching your 1/2-inch ratchet until the plug turns smoothly for several full rotations to prevent cross-threading delicate aluminum threads.
