Universal Spark Plug Gap Tool, 10mm-16mm, Steel Feeler Gauge (Black)

Professional Spark Plug Tool

• Versatile Compatibility: Our SINGARO spark plug gap tool is suitable for most standard spark plugs with 14mm, 12mm, 10mm, and 16mm threads. Ideal for chainsaws, string trimmers, and other small equipment engines. It is not compatible with 18mm thread and long reach or short reach spark plugs.

• Precision Measurement: Built with a dual-marked stainless-steel feeler gauge, the tool boasts a measurement range from 0.001 inch to 0.04 inch (0.03mm to 1mm). The gauge is made from high-quality, flexible 65Mn steel, hardened and polished for accurate and long-lasting usage. Perfect for personal or professional machinery stores and automotive garages.

• Handling Spark Plug Electrodes: Some spark plug electrodes may bounce back due to their material. For a target gap of 0.046 inches, using a 0.044-inch feeler gauge is recommended to achieve the desired result. If your spark plug electrodes exhibit a slight bounce, this tool will still meet your needs in a wide range of applications.

• Ease of Use: Simply place your spark plug in the gapper and select your desired feeler gauge. Slowly screw the knob until the side electrode compresses to the desired gap thickness. Note that this tool only closes a gap; it cannot open one.
