Universal Spark Plug Gap Tool with 32 Blade Steel Feeler Gauge for Most Spark Plugs

1. The SINGAR spark plug gap tool is a professional tool designed for most standard spark plugs, including those with 14mm, 12mm, 10mm, and 16mm sizes. It is especially useful for spark plugs used in chainsaws, string trimmers, and other small equipment engines with short thread depth. Please note that it is not compatible with 18mm thread and 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 that has been hardened and polished for long-lasting and accurate usage. It is highly recommended for use in personal or professional machinery stores and automobile garages.
3. It is important to note that due to the material of the spark plug, some spark plug electrodes may bounce back. This is normal for certain spark plugs. If your desired gap is 0.046in, it is recommended to use a 0.044in feeler gauge size. It is advised to use a smaller scale than the target gap, as this automotive spark plug gap tool is suitable for a wide range of applications.
4. Using the spark plug gap tool is easy. Simply place your spark plug onto the spark plug gapper and use your desired feeler gauge. Then, 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 and will not open a gap.
