Description
The Asimeto Go/NoGo Plug Thread Gauge is a precision internal-thread verifier designed for imperial-size applications. Built for right-hand threads and engineered to ASMEB1.20.1-2013, it delivers quick, reliable checks in quality control and machining environments.
- Size and pitch: Imperial 3/4 x 14 (major diameter 0.75", 14 TPI) for common US-threaded components.
- Go/NoGo capability: Built-in Go and NoGo ends provide immediate pass/fail confirmation on thread depth and integrity.
- 3-step L3 design: Three distinct engagement steps ensure comprehensive depth and tolerance verification along the threaded length.
- Right-hand configuration: Optimized for standard right-hand threads to streamline setup and inspection workflows.
- Standards compliant: Precisely crafted to meet ASMEB1.20.1-2013 internal-thread requirements for consistent results.
- Durable, production-ready tool: Designed for frequent use in machine shops and QA labs with tight tolerances maintained over time.
Use cases include validating tapped holes after tapping operations, ensuring mating parts assemble smoothly, and providing repeatable thread checks across operators. This gauge helps detect under- or over-tapped conditions before assembly, reducing rework and improving first-pass yields in manufacturing and quality control processes.
