Starrett Feeler Gauge Sets


Tool Steel	301 Stainless Steel

Check gaps, alignment, and narrow slots with these feeler gauge sets that include leaves in a variety of thicknesses riveted together in a fan design. Sets fold up for portability. Each leaf is marked with thickness. Leaf-securing locks hold individual gauge leaves in place.

Tool Steel—Tool steel gauge sets are stronger, harder, and more wear resistant than stainless steel.

301 Stainless Steel—Stainless steel gauge sets are less likely to rust than tool steel.

Starrett Feeler Gauge Sets for Tight Spaces

To measure thickness in areas where standard feeler gauges don’t fit, these sets have leaves with narrow ends. They're used to check gaps, alignment, and narrow slots. Sets include leaves in a variety of thicknesses that are riveted together in a fan design that folds up for portability. Each leaf is marked with thickness. Leaf-securing locks hold individual gauge leaves in place.

Tool Steel—Tool steel gauges are stronger, harder, and more resistant to scratches and wear than stainless steel gauges.

Stainless Steel—Stainless steel gauges are less likely to rust than tool steel gauges.

Starrett Feeler Gauge Sets for Tight Spaces with Calibration Certificate

A certificate of calibration traceable to NIST states that these sets have passed a test for accuracy. They’re used to check small gaps, narrow slots, and alignment. The leaves have a narrow end to measure thickness in areas where standard feeler gauges don’t fit. For example, they can measure gaps when setting engine components such as spark plugs to make sure there’s enough space so friction doesn’t lead to inefficiency.

Sets include leaves in a variety of thicknesses that are riveted together in a fan design that folds up for portability. Each leaf is marked with thickness. Leaf-securing locks hold individual gauge leaves in place.

Tool Steel—Tool steel gauge sets are stronger, harder, and more wear resistant than stainless steel gauge sets.

Stainless Steel—Stainless steel gauge sets are less likely to rust than tool steel gauge sets.

Tapered-Width Feeler Gauge Sets

Check slot widths and hole diameters with the markings on these gauges. Leaves in a variety of sizes are riveted together in a fan design—spread them out for use or fold them in for portability. Each leaf narrows toward the tip to measure a range of sizes. Slide them into a hole until the gauge sits snug and then read the width measurement.

Steel—Steel gauges are stronger, harder, and more wear resistant than stainless steel gauges.
