Which Feeler Gauge is Right for You?

If you work in a machine shop you need measuring tools and a good feeler gauge can be invaluable. However, tool making companies manufacture more than one kind. Let’s look at the different feeler gauges available, to help you make the right choice.

What are Feeler Gauges?

Feeler gauges are specially designed measuring tools used to measure distance or clearance between two parts. They are extremely important for machinists performing high tolerance and precision work and auto mechanics. With things like engine components and sophisticated machinery, a few thousandths of an inch or so can make a big difference.

To use a feeler gauge, you simply stick one of its leaves (blades) between the two parts. There is a number on the leaf denoting its thickness.

Straight or Parallel Gauges

This kind of feeler gauge has blades which are completely straight and there is no tapering. The end of the blade is rounded.

Tapered Gauges

A tapered feeler gauge gradually tapers down as it reaches the end of the blade. It doesn’t come to a point but it is much narrower at the end. This allows you to take measurements in very small areas.

Go No Go

If you want to take very accurate readings, a go no go may be your best option. It is specially tapered so only the tip will fit into the gap to be measured. These measuring tools help to simply the process of taking measurements time and time again.

Individual Strips

Single strip gauges are a good idea for the machinist or mechanic who must take the exact same measurement many times during the day. A strip is a single blade and this eliminates opening and closing and searching for the right size blade.

When you need measuring tools, make sure to use a supplier with a reputation for high quality and great service.
