T238 Tools - Gearbox Feeler Gauge

A feeler gauge, also known as a thickness gauge or gap gauge, is a precision measuring tool used to measure narrow gaps or clearances between two surfaces. T238 feeler gauge can precisely measure the clearance between gearboxes and gears, and it can also be widely used in mechanical, automotive, and engineering applications where precise spacing is critical.

How to Use:
1、Select a blade that approximates the expected gap size.
2、Gently insert the blade into the gap. The correct blade should fit with a slight drag or "feel" but without forcing or excessive looseness.
3、If needed, try different blades or combine blades (by stacking) to achieve the precise measurement.

Advantages:
1、Simple, durable, and inexpensive.
2、Provides direct, reliable measurement of clearances.
3、Portable and requires no external power source.
