How to Buy the Best Feeler Gauge

Level of Accuracy

Of course, the first characteristic we must consider is accuracy. It is a tool used to know the most appropriate accuracy.

Here you can have different systems of units. In particular, most tools offer thickness in inches and millimeters.

So, this could make it easier to have the appropriate accuracy. If you want to prevent your tool from losing accuracy, you should consider something important.

Especially these tools are made of metal, such as steel. Therefore, the temperature of this metal should not be raised, as the material can expand.

This could certainly deform your tool.

Quality of Materials

In general, most thickness measurement sets are made of steel.

At best, this steel is hardened and tempered to provide a long service life. So, this feature can be really important to have good use at all times.

Even an anti-rust treatment can complement this durability.

Specifically, a tool without rustproofing can offer a shorter service life. In this case, you should apply lubricating oil to avoid this kind of inconvenience.

If you do not want to go to this trouble, then your tool should be made of stainless steel. Either way, this last option is always much more convenient for you.

Measuring Range

All users need different measurement ranges.

That is why the same measurement range is not always provided in any type of tool. Of course, as these measurement ranges are wider, then it will be more convenient for you.

This is even a fairly common situation when you need to work with an engine or a complicated area in a vehicle.

In the best cases, you can find blades that provide a length of 12 inches. This may be more than enough when you need excellent length. On average, most blades provide a length of only 3 inches.

So, if you don’t have to use this tool in difficult areas, this length might be more than enough.

Design

First of all, we can mention that an efficient design will allow you an easy replacement for each sheet.

Over the lifespan, the blades of this tool can deteriorate, and the level of accuracy decreases. Therefore, an easy locking system will allow you to remove the blades that are damaged and deteriorated.

In this way, you can keep your tool in perfect condition.

On the other hand, we can include the laser engraving system in the design. In particular, this feature only facilitates the work of measuring thickness.
