Industrial Accu-Gage 1-5 8-18 UNEF-3B Thread Plug Gage

Industrial Accu-Gage 1-5 8-18 UNEF-3B Thread Plug Gage is a two-ended external-thread inspection tool (Go and No-Go) used for verifying 8-18 UNEF-3B threads, with a Go end diameter of 1.5889 inches and a No-Go end diameter of 1.6418 inches. This plug gage enables rapid pass/fail checks on mating threads in quality-control workflows, allowing parts to be accepted when the Go limit fits and rejected when the No-Go limit is exceeded. As part of the Accu-Gage lineup, it supports precise reference measurements aligned with UNEF-3B tolerances for external threads and is suitable for use in machining, threading, and assembly processes. Typical applications include inspection of fasteners, fittings, and precision components that require accurate 8-18 UNEF threads, helping ensure proper fit and reliable performance across manufacturing environments.
