The Asimeto Plug Gauge (682 Series) is a precision internal-thread gauge designed for verifying metric fine threads. Built for machinists, inspectors, and quality teams, it delivers reliable go/no-go checks for M48 x 3 right-hand threads at 6H tolerance.

• Series & tolerance: 682 Series plug gauges manufactured to the 6H tolerance class for metric internal threads.
• Thread size & direction: M48 x 3, right-hand thread configuration for standard metric fasteners.
• Precision design: Cylindrical body with ends machined to mirror the test thread’s pitch diameter.
• Grip & durability: Knurled body for secure handling and construction from high-quality materials for long service in busy workshops.
• Ease of use: Quick insertion into a component to verify internal thread engagement and determine accept/reject decisions.
• Application: Ideal for quality control in manufacturing, assembly, and maintenance where metric fine threads are used.

Using this gauge helps you confirm thread fit before assembly, reducing misfits and costly rework. The 6H-compliant pitch-diameter verification provides confidence in part compatibility, while the sturdy build delivers consistent performance across daily shop use. Perfect for production-line inspections, maintenance checks, and incoming quality control of metric fasteners.
