Plug Gages — New & Used

Plug gages (also called plug gauges or go/no-go gages) are used to quickly verify hole size, location, and thread quality in production parts. From plain plug gages for smooth bores to thread plug gages for internal threads, they provide a simple pass/fail check that keeps machining, assembly, and quality processes on spec.

At Surplus Select, we stock a rotating selection of new and used OEM plug gages including GO/NO-GO sets, master plugs, and specialty sizes. Our inventory updates daily, offering surplus pricing for machine shops, inspection labs, and manufacturers who need reliable gauging without full metrology list pricing.
