SATA GL09405 23-Piece Feeler Gauge Set 0.02-1.00mm

The set covers 0.02 mm to 1.00 mm, providing a wide range for measuring clearance and gaps in engines, transmissions, bearings, and other mechanical assemblies. This helps you select the closest blade that fits snugly, ensuring accurate measurements across common automotive and mechanical tasks.

Each blade has a clear thickness marking printed on it. Compare the blade to the gap you’re measuring and select the blade whose marking fits snugly in the opening without forcing it.

Yes, the blades have tapered ends to improve access in tight or recessed gaps. This design helps you insert the blade more easily and measure gaps in confined spaces without bending or damaging the blade.

The blades are constructed from high-quality steel with corrosion-resistant properties (stainless steel construction is noted in the specs), providing durability and longevity in challenging environments.

The blades are 4 inches (100 mm) long. This length offers a balance between reach and control, enabling measurements in standard automotive and mechanical tasks while staying manageable in tight spaces.

It’s ideal for automotive maintenance (valve clearances, gasket gaps), engine tuning, mechanical inspections, and other precision-gap measurements in machinery and assemblies.

after use, wipe blades clean and keep them dry. Store the blades on the included holder to protect edges and keep markings readable. Periodic light lubrication can help prevent rust, especially if the set is stored in a humid environment.

Absolutely. The set is suitable for any precision-gap work, including machining, mechanical assembly, and other tasks where accurate clearance measurements are needed.

Handle blades with care to avoid cuts, work slowly to prevent bending edges, and wear eye protection when working around moving parts or hot components. Ensure the workpiece is secure before testing gaps.

This set offers a broad 0.02–1.00 mm range, high-precision blades, durable steel construction, and a compact, organized holder. Other sets on Fepy may offer more or fewer blades, different blade lengths, or alternate materials. Choose based on the required measurement range, workspace, and how you value organization and durability.

Regularly inspect blades for nicks or bends, clean residue after use, dry thoroughly, and apply a small amount of light oil if stored for extended periods. Replace any blade that shows significant wear or damage to maintain accuracy.
