Threaded Plug Gauges
Available559 products
Threaded plug gauges, also called thread plug gauges, thread gauges, or simply plugs, are used to check and inspect internal threads by attempting to mate the Go and No-Go gauge members to the threaded part. If the fastener turns on the gauge smoothly with no binding, the user will know it is falls within the specific tolerance. All gauges are marked with nominal size and gauge type, and are right-handed unless stated otherwise.

These threaded plug gauges are used to check and inspect internal inch threads in Unified thread standards including Unified Coarse (UNC), Unified Fine (UNF), and others. Individual Go or No-Go gauge members are available or assemblies with one- or two-gauge members with a handle.
