4336M/A-Magnetic Spark Plug Socket (12 Point)-½” Drive

4336M/A Series is built for mission-critical engine service:

• High-Strength Magnetic Integration: The defining technical feature. An internal magnetic ring is permanently seated in the socket bore. This provides a consistent, high-tension hold on the spark plug that does not degrade over time, unlike rubber inserts that dry out or springs that can lose tension.
• 12-Point (Bi-Hex) Geometry: Engineered for maximum versatility. The 12-point internal profile allows the socket to engage both standard 6-point hex plugs and specialized 12-point spark plugs found in modern European and high-performance engines.
• Thin-Wall Architecture: Precision-machined to have a reduced outer diameter. This ensures the socket can enter narrow spark plug tubes where standard deep sockets would bind against the cylinder head walls.
• Forged Chrome Vanadium (Cr-V) Metallurgy: Forged and heat-treated to professional industrial standards. This provides the structural rigidity needed for high-breakout torque while maintaining a slim profile.
• Dual-Standard Loadouts: Available in metric and SAE equivalents, including the critical 14mm, 16mm, and 21mm sizes to cover the entire automotive and industrial spectrum.
