Questions about this product
- What are the exact thickness measurements included in this 17-blade set?
- The set includes 17 metric blades ranging from 0.02 mm to 1.00 mm. You get sizes from 0.02 to 0.10 mm, plus 0.15, 0.20, 0.25, 0.30, 0.40, 0.50, 0.75, and 1.00 mm. Each blade has its thickness clearly etched on the surface for quick identification.
- What materials are used to make these feeler gauges?
- The blades are made of hardened spring steel with a polished finish for extra durability. They are housed in a nickel-plated steel holder with a convenient thumb screw for adjusting blade retention. This construction ensures the tool holds up well to repeated mechanical use.
- How do I keep these steel feeler gauges from rusting over time?
- Since these hardened spring steel blades have moderate corrosion resistance, you should keep them clean and dry. Wipe each blade down after use to remove dirt, grease, or fingerprints. Applying a light coat of machine oil before folding them back into the holder prevents rust.
