Universal Spark Plug Gap Tool for 10mm, 12mm, 14mm, 16mm Spark Plugs

1. SINGARO Spark Plug Gap Tool: This professional tool is designed for most standard spark plugs, including 14mm, 12mm, 10mm, and 16mm sizes. It is particularly useful for short thread depth plugs commonly found in chainsaws, string trimmers, and other small equipment engines. Please note that it is not compatible with 18mm thread or long reach/short reach plugs.
2. Precise Measurement: The dual marked stainless-steel feeler gauge has a measurement range from 0.001 inch to 0.04 inch (0.03mm to 1mm). Made of high-quality flexible 65 manganese steel, it is hardened and polished for long-lasting and accurate usage. This tool is a must-have in any personal or professional machinery store or automobile garage.
3. Helpful Tip: When using the spark plug gap tool, keep in mind that some spark plug electrodes may bounce back slightly, which is normal for certain spark plugs. If your desired gap is 0.046 inch, it is recommended to use a 0.044 inch feeler gauge size. It's better to start with a smaller scale than the target gap, as this tool is versatile and suitable for a wide range of applications.
4. Easy Operation: Using the spark plug gap tool is simple. Just place your spark plug onto the tool, select your desired feeler gauge, and slowly screw the knob until the side electrode compresses to the desired gap thickness. Please note that this tool is designed to close a gap, not to open one.
5. Package Contents: This package includes 1 SINGARO spark plug gap tool.
