Feeler Gauge Sets

With Flat Round Leaves
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.
