SATA ST09407SJ 32-Piece Feeler Gauge Set

The set includes 32 gauges with thicknesses ranging from 0.02 mm to 1.00 mm. Each blade is clearly stamped with its thickness for quick identification, and the blades are 3.5 inches long.

The thin, flexible blades are designed to access restricted gaps and tight spaces found in engines and machinery, making it easier to obtain an accurate reading in hard-to-reach areas.

The gauges are made from high-quality stainless steel, providing corrosion resistance and durability for repeated use over time.

Each blade has the thickness clearly stamped on it in millimeters, so you can identify the gap size at a glance.

It's ideal for automotive tasks (engine clearances, valve gaps), mechanical work (machinery settings, shims), and precision woodworking where exact gaps are needed.

1) Clean the gap area. 2) Choose a gauge slightly smaller than the suspected gap. 3) Gently insert the gauge until it seats with a light drag. 4) Remove and read the thickness marked on the blade. 5) Repeat with other sizes to confirm and record the measurement.

Yes. Handle the gauges with care, use the smooth edges to avoid cuts, don’t force gauges into tight spaces, and store them properly after use to prevent damage.

Keep all gauges in the included storage case to stay organized and protected from moisture and corrosion; store in a dry place and wipe any residue after use.

Compared with the SATA 24-Piece Feeler Gauge Set and the SATA 16-Piece Feeler Gauge Set, this 32-Piece set offers a broader range of sizes for more versatility, while the smaller sets are more portable. Best choice depends on how wide a range you need in your work.
