The Asimeto Ring Thread Gauge (NoGo) — Metric, Right Hand, 6g — is a precision check tool designed for machinists, quality control technicians, and assembly teams who need to verify metric threads to exact limits. This NoGo gauge from the 686 Series confirms the maximum pitch diameter for M18 x 2 right-hand threads, helping ensure only properly sized fasteners are used.

• 6g tolerance class: precise measurement of the thread pitch diameter to the 6g standard.
• NoGo designation: verifies the thread diameter is within allowed limits; if the fastener cannot pass through, it’s out of tolerance.
• Thread specification: metric M18 x 2, right-hand threads, designed to match common fasteners.
• 686 Series construction: engineered for durability and long-lasting performance in demanding shop environments.
• Design details: knurled outer rim provides a secure grip; a red datum marker aids quick orientation during measurements.
• Finish and material: manufactured with high-quality materials for reliable, repeatable gauge checks.

With the Asimeto 686 Series NoGo ring gauge, inspectors can rapidly determine whether a fastener’s pitch diameter fits within the maximum limit, reducing the risk of oversized threads entering assemblies. This leads to safer, more reliable connections, faster quality checks, lower rework, and improved consistency across production runs. Ideal for manufacturing floors, maintenance workshops, and QC laboratories where precise metric threading matters.
