Industrial-Grade Stainless Steel Construction:Combines 301 & 420 martensitic stainless steel blades – corrosion-resistant up to 5x longer than standard gauges. Magnetic properties ensure secure placement during valve/spark plug measurements, eliminating lubrication needs even in high-humidity environments.
48 Dual-Marked Blades for Universal Precision:48 laser-etched blades (0.03-1.00mm / 0.001"-0.508") cover 98% of automotive/industrial specs, including ultra-thin 0.03/0.04mm for modern hybrid engines. Offset blades access tight spaces like piston ring grooves without disassembly.
Error-Proof Measurement System:Interlocking blade design prevents accidental slippage during critical measurements. Laser-etched markings withstand 10,000+ wipe cycles – 50% more durable than standard engraving.
Workshop-to-Field Ready Design: Rotating hinge allows 180° blade deployment or compact folding Detachable keychain module keeps critical blades (0.05-0.08mm) accessible during engine diagnostics.
Built for Pros: The feeler gauge set covers a wide range of gap sizes for engines, pistons, valves, and bearings—an essential tool for mechanics and serious DIYers, complete with a protective case.
