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

1. The SINGARO spark plug gap tool is a professional tool designed for most standard spark plugs, including 14mm, 12mm, 10mm, and 16mm sizes. It is especially useful for short thread depth plugs commonly used in chainsaws, string trimmers, and other small equipment engines. Please note that this tool is not compatible with 18mm thread, long reach, or short reach spark plugs.
2. This tool features a dual marked stainless-steel feeler gauge with a measurement range from 0.001inch to 0.04inch (0.03mm to 1mm). The feeler gauge is made of high-quality flexible 65 manganese steel, hardened and polished for durability and accuracy. It is the preferred tool for any personal or professional machinery store or automobile garage.
3. When using the tool, keep in mind that some spark plug electrodes may bounce back due to the material of the spark plug. If your desired gap is 0.046in, it is recommended to use a 0.044in feeler gauge size. Using a slightly smaller scale than the target gap is advised. This automotive spark plug gap tool is versatile and suitable for a wide range of applications.
4. The tool is easy to use - simply place your spark plug onto the spark plug gapper and select your desired feeler gauge. Then, slowly screw the knob until the side electrode compresses to the desired gap thickness. It is important to note that this spark plug gap tool is designed to close a gap, not open it.
5. The package includes one spark plug gap tool.
