12-Point Spark Plug Socket with Magnet, 3/8-Inch Drive, 16mm, 250mm Length

Overview

This long-reach spark plug socket is engineered for reliable spark plug removal and installation on modern engines. The integrated magnet securely grips the spark plug during extraction, eliminating fumbling and reducing the risk of dropped components in tight engine bays. The 12-point profile ensures positive engagement without cam-out, while the extended 250mm length provides the reach needed for recessed spark plug wells on many contemporary powertrains.

Compatible alternatives include deep-well magnetic spark plug sockets for different drive sizes, or spark plug thread repair kits for damaged cylinder head applications.

Key Features

• 12-Point Internal Profile – Precise contact with spark plug hex geometry; reduces rounding risk and ensures controlled engagement
• Integrated Magnet – Holds spark plug securely during removal and reinsertion; prevents loss in engine compartments
• 250mm Extended Length – Reaches spark plugs in deep wells and recessed engine positions
• 3/8-Inch Square Drive – Standard drive size compatible with all 3/8-inch ratchets and extensions
• 16mm Socket Bore – Fits standard automotive spark plugs (14mm and 16mm plug sizes across most applications)
• Brass-Lined Socket End – Durable insert protects spark plug electrodes and ceramic insulator during handling
• Knurled Drive End – Textured grip collar improves control and prevents slipping during torque application
• Satin Chrome Finish – Resists corrosion and maintains appearance through repeated shop use

Business Advantages

Stock this as a core item. Spark plug maintenance is a recurring service revenue stream across automotive, small engine, and lawn equipment repair. The magnetic retention feature eliminates callbacks due to broken or dropped plugs during installation—a common frustration point for technicians.

The 250mm length makes this the go-to choice for late-model engines with deep or offset spark plug wells. Position this alongside alternative bore sizes to capture the full service breadth of your customer base.

Margin-friendly and high-turnover: mechanics will want 2–3 units in their toolbox for different engine configurations.
