Feeler guages set. For example: adjust the valves on motorcycles. Insert the feeler gauge set into the gap; the optimal fit is when it can be moved back and forth smoothly. Filler gauge are professionally finished with no burrs, allowing safe, accurate, and repeatable stacking or gap tests.

The long straight blades reach deep grooves and confined spaces, while the angled blades access tight and hard-to-reach spots with ease. Each thickness gauge blade is polished to reduce friction, improve insertion feel, and enhance wear resistance.
