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.
Tapered leaves are often used for go/no-go checks. The end of each leaf is 0.002" thinner than its listed thickness. If the tip fits but the rest of the body doesn’t, your gap is within tolerance. Offset leaves are angled to access gaps that flat leaves can’t reach.
Steel and tool steel leaves are stronger, harder, and more wear resistant than stainless steel and brass leaves. Brass leaves have good corrosion resistance and are nonmarring to prevent scratches. They’re also nonmagnetic, so you can safely check spark plugs and other electronic ignitions without attracting debris. Stainless steel leaves are less likely to rust than steel and tool steel leaves.
Sets with both steel and brass leaves include 30 steel leaves and six brass leaves.
Sets with a leaf-securing lock hold individual leaves in place so they don’t move and disrupt measurements.

Color-Coded Feeler Gauge Sets
With leaves that are color coded based on thickness, you can read your measurements at a glance. These gauge sets are used to check gaps, alignment, and narrow slots. Gauge leaves are riveted together in a fan design to keep the set complete; the set folds up for portability. Sets are nonmagnetic, nonmarring, noncorrosive, nonsparking, and resistant to oil.

Combination Wire, Width, and Thickness Feeler Gauge Sets
These sets combine a wire gauge, a tapered-width feeler gauge, and a set of feeler gauges for tight spots in one tool. The tapered-width gauge is designed for measuring hole and slot widths and diameters. The feeler gauge leaves check the thickness of slots, gaps, and alignment; each leaf is marked with thickness. Leaves are riveted together in a fan design that folds up for portability.

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 gauges are stronger, harder, and more wear resistant than stainless steel gauges.
Stainless steel gauges are less likely to rust than steel gauges.

Feeler Gauge Sets for Tight Spots
Leaves have narrow ends to measure thickness where standard feeler gauges can’t fit. These sets are for checking gaps, alignment, and narrow slots. They include leaves in a variety of thicknesses 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.
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.

Coating-Thickness Gauge Inspection Kits
With three included probes, the gauge in these kits goes beyond a typical check for coating thickness. It also measures surface profile and environmental conditions, such as temperature. Kits include everything you need for thorough tests whether you’re inspecting a surface that’s painted, powdered, or plated. Just swap out probes to measure what you need. Use the plate and shims to practice measurements and ensure the probe is working properly. The glass plate and metal shims work with the surface profile probe. The plastic shims work with the coating thickness probe. Easy to use, the gauge’s touch screen guides you through measurements step-by-step.
Switch between scan modes for full control over how you measure, from single-point tests to continuous readings. You can even find stats and create presets for repeated measurements. For long-term tracking, the gauge stores up to 250,000 results from multiple probes in up to 1,000 batches. See trends in real time with live graphing. To help you comply with ISO, ASTM, SSPC-PA, and IMO coating standards, set criteria for go/no-go tests.
Thanks to a compatible app, you can add notes and images to readings or make reports on the go. For exporting into programs such as Excel or making multimedia reports in templates, use the included software.
Choose kits based on coating and surface types. Kits with probes for both nonconductive and nonmagnetic coatings include a thickness probe that automatically identifies the coating and surface material. Kits with probes for 0-250 mil coating thickness are ideal for testing epoxies, flame-retardant finishes, and other thick coatings.
A built-in probe lets you use the gauge one-handed—no extended probe to maneuver. A detachable probe means you can measure underwater and up to 3 ft. away. The waterproof probes are at the end of sealed cable, so you can reach surfaces without submerging the gauge.
