Teng Tools builds this metric blade-style measuring tool to handle the clearance checks professional technicians face every day. With blades spanning 0.05 mm to 1.0 mm and a 100 mm blade length, it fits comfortably in your hand and reaches into the tight spots common in modern engine bays. Each blade is individually stamped with its metric thickness, so identification is instant even under the hood on a dim shop floor. The fan-style holder keeps every blade organized and protected when the tool is closed, and lets you isolate a single blade — or stack several — to match the exact clearance you need. Weighing just 88 g, this tool adds almost nothing to your carry weight yet covers a wide measurement range. Use it for valve lash, spark plug electrode gaps, piston ring end-gap, contact-point settings, bearing clearances, and surface-flatness verification against a straight edge. Whether you work on cars, motorcycles, marine engines, or industrial machinery, accurate clearance measurement is fundamental to correct assembly. A reliable gap-checking tool belongs in every technician's kit, and the Teng Tools name means you are reaching for a brand that professional tradespeople around the world trust for precision hand tools.
