Koken 3305PZ-16 3/8" Drive Z-Series 12-Point Magnetic Spark Plug Socket 16mm

The Koken 3305PZ-16 is a professional-grade 3/8" square drive spark plug socket designed for precision and accessibility in tight engine compartments. This 16mm, 12-point metric socket features Koken's innovative Z-Series magnetic retention system for secure spark plug handling.

Key Features:

• Thin wall design for superior access in confined spaces
• Integrated magnetic spark plug retention system
• Compact profile compared to rubber insert or clip-type designs
• 12-point opening for versatile spark plug engagement
• 3/8" square drive compatible with standard ratchets and extensions
• 16mm size for metric spark plug applications

The magnetic retention mechanism uses a small, reliable magnet instead of bulky rubber inserts or metal clips, allowing for a slimmer socket profile. This design innovation enables the socket to fit into areas where traditional spark plug sockets cannot reach, making it ideal for modern engines with limited clearance around spark plugs. The 12-point design provides multiple engagement positions for easier alignment in restricted access situations.
