Insize feeler gauge tape is a precision thickness shim material supplied in convenient roll form for measuring, setting, spacing and clearance adjustment applications. Designed for situations where standard leaf feeler gauges cannot reach or where a continuous length of accurate shim stock is required, this tape can be cut to size for custom gap measurement and packing tasks. It is widely used in machining, toolmaking, maintenance, automotive service, assembly work and precision engineering. The consistent thickness along the full length allows reliable checking of tolerances, alignment, bearing clearances, gear backlash, and machine setup. The roll format makes it ideal for workshop environments where flexible, on-demand shim material is needed.
