Feeler Gauge Sets
Keep a variety of leaf thicknesses on hand to confirm gaps are within tolerance. These gauges are often used to check the clearance around bearings and other machine parts, making sure there’s enough space to avoid friction and prevent wear. The leaves are riveted together in a folding fan design, so they’re easy to carry. Each leaf is marked with thickness for quick reference.
Stainless steel leaves are less likely to rust than steel and tool steel leaves.
Sets with a leaf-securing lock hold individual leaves in place so they don’t move and disrupt measurements.

Starrett Feeler Gauge Sets with Calibration Certificate
To ensure accurate readings, these sets come with a certificate of calibration traceable to NIST that states they’ve passed a test for accuracy. They are used to check gaps, alignment, and narrow slots. Gauge leaves 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.
Stainless steel gauge sets are less likely to rust than tool steel gauge sets.

Starrett Feeler Gauge Sets for Tight Spots 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.
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.

Tapered-Width Feeler Gauges
Confirm slots, holes, and mating surfaces on parts are properly sized. Narrow at one end, these feeler gauges measure a range of sizes. Slide them into a hole until the gauge sits snug and then read the width measurement. All have a range of width markings for quick reference. Made of either stainless steel or plastic, they resist corrosion.
