Product Information

Full details

The BlueSpot 32 Blade Feeler Gauge (02084) is an essential precision measurement tool designed for mechanics, engineers, and DIY enthusiasts who require accurate clearance checks for engine components and machine assembly. Its primary strength lies in its wide measurement range and inclusion of both imperial and metric increments, though users should be mindful that the carbon steel construction requires regular maintenance to prevent oxidation if stored in damp conditions.

FAQs

What is the smallest measurement this gauge can read?

The smallest measurement is 0.0015 inches or 0.038 millimeters.

Why is one blade made of brass?

The brass blade is used for non-sparking applications or when you need to avoid scratching delicate components.

Are the blades removable?

Yes, the blades are held together by a nut and bolt, allowing you to remove or reorganize them if needed.

Does this gauge work for motorcycle engine valves?

Yes, the gauge is suitable for any application requiring precise clearance checks within the provided size range.

How do I ensure the gauge stays accurate?

Avoid forcing the blades into gaps that are clearly smaller than the blade size, as this can bend or deform the steel.

Troubleshooting

Measurements are hard to read

Wipe the blades with a clean cloth to remove grease, then use a permanent marker on the etched labels if they remain faint.

Surface rust appearing on blades

Remove existing rust with a fine-grade abrasive pad and immediately coat with machine oil to protect the metal.

Blade fanning is too stiff or too loose

Adjust the tension by tightening or loosening the screw at the base of the gauge handle.

Pros and Cons

Pros

  • Covers a wide range of clearance sizes
  • Easy-to-read etched markings
  • Includes a non-marring brass blade
  • Heat-treated steel ensures long-term calibration accuracy

Cons

  • Carbon steel is prone to rust if not kept lightly oiled
  • Requires careful cleaning between uses
  • Not intended for heavy-duty prying

Setup, Compatibility & Care

To use the tool, loosen the thumb nut to fan out the required blades. Select the desired thickness and slide it into the clearance gap; it should feel a slight resistance but not force. After use, ensure the blades are wiped clean of oil and debris. Because the product is made of carbon steel, apply a light coat of machine oil to the blades before folding them back into the handle to prevent surface rust during storage. Store in a dry, room-temperature environment.
