Collection: Go / No Go (PLUG)

Essential for rapid bore inspection and quality control, Go/No-Go plug gauges provide instant pass/fail verification of hole diameters without complex measurement procedures. Whether you're checking drilled holes, reamed bores, or machined cavities, these precision gauges eliminate guesswork and ensure consistent quality. The 'Go' end verifies minimum diameter while the 'No-Go' end checks maximum diameter, providing complete dimensional verification in seconds. These cost-effective inspection tools help maintain tight tolerances and reduce scrap rates across production and quality control operations. Built with hardened steel construction and precision ground surfaces for reliable, repeatable results. With access to over 50,000 products, we can source exactly what you need.
