The Asimeto Plug Gauge Kit – GO & NOGO is a focused metric-thread verification toolset designed for machinists, toolmakers, and quality control teams. It provides fast, reliable checks of internal thread tolerances across common metric sizes.

• Size range: Includes M3, M4, M5, M6, M8, M10, and M12 gauges for comprehensive coverage.
• Dual-ended design: Each gauge features GO and NOGO ends to streamline quick pass/fail assessments.
• Go/No-Go functionality: GO end verifies the minimum bore size, while the NOGO end confirms the maximum limit, helping prevent undersized or oversized threads.
• Durable construction: Precision-engineered from high-quality materials to withstand the rigors of demanding workshop environments.
• Ready-to-use set: A complete metric range for instant compatibility checks during setup, inspection, and assembly.

With this kit, you can quickly determine if internal threads meet the intended tolerances before assembly, reducing guesswork and rework. The GO/NOGO approach delivers clear, objective results, helping you maintain consistent quality, shorten setup times, and protect mating parts from improper engagement. The all-in-one M3–M12 collection is ideal for CNC operators, mechanical assemblers, maintenance technicians, and workshop teams who value precise, repeatable thread verification without complex measuring equipment.
