Universal Spark Plug Gap Tool with 32 Blade Feeler Gauge for 10mm 12mm 14mm 16mm Spark Plugs

1. SINGARO Professional Spark Plug Gap Tool is designed to work with 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. This tool features a dual marked stainless-steel feeler gauge with a measurement range from 0.001 inch to 0.04 inch (0.03mm to 1mm). Made of high-quality flexible 65 manganese steel, the feeler gauge is hardened and polished for long-lasting and accurate usage. It is the preferred product for both personal and professional use in machinery stores and automobile garages.
3. Keep in mind that due to the material of some spark plugs, the electrodes may bounce back, which is normal. If you are aiming for a gap of 0.046 inches, it is recommended to use a 0.044-inch feeler gauge size. Using a smaller scale than the target gap is advised, and this spark plug gap tool is versatile enough to meet a variety of applications.
4. Using the tool is simple – place your spark plug onto the spark plug gapper, choose your desired feeler, and slowly screw the knob until the side electrode compresses to the desired gap thickness. It is important to note that this tool is designed to close a gap, not open one.
5. Customer satisfaction is our top priority. If you have any questions or concerns about the product, please don't hesitate to contact us. We are committed to providing you with satisfactory solutions in a timely manner.
