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.
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.
Sets with a leaf-securing lock hold individual leaves in place so they don’t move and disrupt measurements.

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