Industrial UNRF-3B Thread Plug Gauge Go No Go is a precision tool used to verify internal 8-18 UNRF-3B threads. This Go/No-Go plug gauge features a Go size of 0.5889 in and a No-Go size of 0.5934 in, enabling quick pass/fail checks for threaded holes. In practice, a hole should accept the Go gauge but not the No-Go gauge, ensuring compliance with the UNRF-3B thread tolerance during machining and quality control. Designed for industrial applications, it supports consistent thread engagement and inspection in manufacturing environments that use 8-18 UNRF-3B threads.
