The document describes a 32-blade feeler gauge set made of stainless steel. The feeler gauge blades measure thicknesses and gaps in both metric and imperial units, ranging from 0.0015 inches to 0.035 inches and 0.04 mm to 0.88 mm. The sizes are etched onto the blades for easy identification. The feeler gauge set can be used to measure gap widths and thicknesses for applications like machinery maintenance and repair.
