The Asimeto 682 Series Plug Thread Gauge is a precision internal-thread gauge designed for quick, reliable verification of metric fasteners. Sized for M12 x 1.25 right-hand threads, it’s ideal for quality control, machining, and assembly environments that require accurate pitch-diameter checks.

• Series: 682 Series plug gauge for internal metric threads
• Thread size and handedness: M12 x 1.25, right-hand
• Tolerance: 6H tolerance class for accurate pitch diameter measurements
• Construction: Knurled cylindrical body with precisely machined ends for secure handling and repeatable checks
• Material and finish: Built from high-quality steel with a durable, long-lasting finish
• Application: Used to measure and verify the pitch diameter of internal metric threads in fasteners

Use this gauge to confirm the pitch diameter of internal threads during production, inspection, or maintenance. The 6H tolerance ensures consistency across batches, helping to prevent mismatches between threaded holes and fasteners. Its rugged construction and knurled grip support reliable use in busy workshop environments, while the precisely machined ends provide quick, repeatable checks for M12 x 1.25 components. Ideal for machine shops, QA labs, and maintenance teams that require precise internal-thread verification.
