Description

The Asimeto Plug Thread Gauge (D/E) is a precision metric coarse-thread plug gauge designed for reliable internal thread inspections in machining and quality control environments. Built for right-handed M30 x 3.5 threads, it delivers consistent go/no-go checks with the dependable 6H tolerance class.

  • End configuration: Dual ends (D and E) on a single gauge body for quick, on-the-spot dual checks without swapping tools.
  • Thread specification: Metric coarse thread, M30 x 3.5, right-hand orientation to align with standard manufacturing practices.
  • Tolerance class: 6H tolerance to ensure precise, repeatable internal-thread verification across production runs.
  • Series and material: 680 Series gauge with robust construction using durable steel and protective finishing for longevity.
  • Go/No-Go functionality: Designed to provide fast acceptance checks, helping operators confirm proper fit at a glance.
  • Durability: Built to withstand repeated use on busy shop floors, maintaining accuracy over time.

With the Asimeto 680 Series plug gauge, you gain reliable control over thread quality in critical assemblies. The dual-ended design reduces setup time, while the 6H tolerance offers tight, repeatable measurements that minimize scrap and rework. Ideal for CNC and manual machining, assembly lines, and quality laboratories, this gauge supports consistent mating with M30 x 3.5 components and helps maintain dimensional integrity across production runs. Proper handling, cleaning, and storage will preserve accuracy and extend the gauge’s life for years of dependable performance.
