SPECIFICATIONS: This set includes two types of feeler gauges. The tapered gauge has 32 blades with a tapered profile to allow for access into tight places. The Offset gauge has 16 blades with an offset design that’s great for awkward areas. Each blade is marked with both metric and SAE sizing, and each set folds neatly into itself for easy transportation and storage. These gauges let you measure tappet clearances, spark plug gaps, bearing clearances, piston ring gaps and more. | TAPERED GAUGE SIZES: Inch - 0.001, 0.0015, 0.002, 0.0025, 0.028, 0.003, 0.0035, 0.004, 0.005, 0.006, 0.007, 0.008, 0.009, 0.01, 0.012, 0.013, 0.014, 0.015, 0.016, 0.018, 0.02, 0.022, 0.024, 0.025, 0.026, 0.028, 0.030, 0.032, 0.034, 0.034, 0.040 (Metric - 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, 0.09, 0.10, 0.13, 0.15, 0.18, 0.20, 0.23, 0.25, 0.28, 0.30, 0.33, 0.35, 0.38, 0.40, 0.45, 0.50, 0.55, 0.60, 0.63, 0.65, 0.70, 0.75, 0.80, 0.85, 0.90, 1.00mm) | OFFSET GAUGE SIZE: Inch - 0.005, 0.006, 0.007, 0.008, 0.009, 0.010, 0.011, 0.012, 0.013, 0.014, 0.015, 0.016, 0.017, 0.018, 0.019, 0.020 (Metric - 0.127, 0.152, 0.178, 0.203, 0.229, 0.254, 0.279, 0.305, 0.330, 0.356, 0.381, 0.406, 0.432, 0.457, 0.483, 0.508mm) | RELIABLE | EFFECTIVE | EFFICIENT: Users trust ARES to be quality tools.
