The Asimeto Ring Thread Gauge (NoGo) is a precision metric gauge designed for right-hand, metric coarse 6g threads, specifically sized M20 x 2.5. It delivers a reliable Go/NoGo check on the shop floor, helping you verify that threaded parts stay within the lower size limit and do not exceed the maximum allowable size.

• Series: 684 Series, calibrated for metric coarse 6g threads
• Thread Type: Right-hand metric coarse 6g, M20 x 2.5
• NoGo Function: Checks minimum material condition to ensure the part remains at or above the lower size limit
• Construction: Hardened steel with a knurled outer edge for secure grip and durability
• Usage: Ideal for incoming inspection, in-process checks, and final QC of threaded components

Using this gauge on parts that must not be larger than the maximum allowable size ensures consistent thread engagement, reduces the risk of assembly issues, and minimizes scrap. The 684 Series NoGo ring provides precise, repeatable results, helping you maintain tight dimensional control across production runs and quality checks.
