3305MS/AS is a professional-grade ⅜” Drive Spark Plug Socket engineered for the delicate task of removing and installing spark plugs in modern internal combustion engines. This series features a Deep-Wall 6-Point (Hex) internal profile that provides maximum surface contact with the plug’s metal base, reducing the risk of slippage. Each socket is equipped with a high-durability Internal Rubber Insert that cushions the ceramic insulator and securely grips the plug for easy extraction from deep engine wells. Forged from premium Chrome Vanadium (Cr-V) steel, these sockets are built to withstand high heat and chemical exposure in professional automotive environments.

Feature
- Why choose a 6-point over a 12-point spark plug socket? A 6-point (Hex) socket provides thicker walls and more surface contact on the spark plug’s hex flats. This is critical for older or slightly rusted plugs where a 12-point socket might slip and crack the ceramic.
- Is the rubber insert replaceable? Yes, the high-quality rubber insert is designed for longevity, but it can be inspected and cleaned to ensure it continues to provide a firm grip on the spark plug terminal.
- Why is the knurling on the socket base useful? Spark plugs should always be started by hand to avoid damaging the cylinder head threads. The knurled ring on the 3305 series provides a non-slip grip for your fingers even when they are covered in engine oil.
- What is the difference between MS and AS? MS stands for Metric Standard (e.g., 16mm), commonly found on European and Asian vehicles. AS stands for American Standard (SAE, e.g., 5/8″), common on classic or domestic US engines.
