3336M/A is a specialized 12-Point Magnetic Spark Plug Socket engineered for high-precision automotive MRO (Maintenance, Repair, and Operations). Designed for a ⅜” Square Drive, this tool is architected to service modern, thin-wall spark plug configurations. Unlike traditional rubber-insert sockets that can perish or lose grip, the 3336M/A utilizes an integrated Magnetic Retention System to ensure the spark plug remains securely seated during both extraction and installation in deep cylinder head wells.

Feature
Technical Architecture & Mechanical Logic
- 12-Point (Bi-Hex) Thin-Wall Geometry: This spark plug socket features a 12-point internal profile. This mechanical logic allows for engagement with both 6-point and 12-point spark plugs, common in modern European and Japanese engines. The thin-wall design is critical for accessing plugs in cramped engine bays where standard sockets cannot fit.
- Integrated Magnetic Retention: Features a high-power magnetic ring that holds the spark plug terminal securely. This eliminates the risk of “dropping” a plug into the cylinder well, which can lead to cracked ceramic insulators or closed electrode gaps.
- Premium Chrome Vanadium (Cr-V) Steel: Forged from high-density, heat-treated Chrome Vanadium steel. This metallurgy provides the structural rigidity and torsional strength required for removing seized plugs without the risk of the socket wall splitting.
- Metric Size Availability: As per the technical data, the 3336M-A is available in the two most critical automotive sizes: 14mm and 16mm.
- 63mm Functional Length: The 63mm total length is optimized for standard spark plug heights, ensuring full engagement of the hex while maintaining a compact profile for use with various extensions.
- Mirror-Chrome Protective Finish: The exterior is treated with a high-polish chrome finish for maximum resistance to oxidation, grease, and workshop chemicals.
B2B Procurement & Workshop ROI
- Enhanced Safety and Reliability: The magnetic core outlasts traditional rubber bungs, providing consistent retention force over thousands of cycles, reducing the labor cost associated with damaged or dropped spark plugs.
- Universal 3/8″ Compatibility: Precision-machined to international standards, ensuring a zero-tolerance fit with all 3/8″ ratchets, extensions, and torque wrenches.
- Professional Inventory Control: Clear laser-etched markings on the socket body allow for rapid size identification in fast-paced service environments.
FAQ Section
- Is this a magnetic socket? Yes. The “A” in the 3336M-A designation indicates the Magnetic version, providing superior plug retention compared to standard friction-fit sockets.
- What is the benefit of a 12-point socket for spark plugs? Many modern vehicles (such as BMW, Mini, and Mercedes-Benz) use 12-point plugs. This socket is compatible with both those and standard 6-point plugs.
- What sizes are available in this series? According to the technical table, the series includes 14mm and 16mm sizes.
- Can I use this with an impact wrench? No. This is a chrome-plated hand-tool socket. For power tool use, Made in Taiwan Chrome Molybdenum (Cr-Mo) impact sockets are required.
