Description
Designed for metric coarse threads, the JBO Thread Plug Gauge provides fast, reliable Go/No-Go checks for threaded holes. It covers right-hand M2 x 0.4 threads within the 6G class, helping machinists, quality teams, and assembly workers verify fit and function with confidence. Crafted from hardened steel, this gauge is built to endure daily workshop use and maintain accuracy over many inspections.
- Go/No-Go Design for Fast, Confident Hole Verification: The two-ended gauge lets you quickly confirm correct thread engagement (go) and detect oversize holes (no-go), speeding setup and reducing rework.
- Metric-Coarse Focused for M2 x 0.4, 6G Threads: Specifically engineered for the common metric coarse thread standard, delivering precise checks that align with real-world part tolerances.
- Hardened Steel Construction for Long-Lasting Durability: Built to withstand routine use in busy shops, resisting wear to protect accuracy over time.
Using the JBO Thread Plug Gauge streamlines quality checks, minimizes guesswork during assembly, and helps maintain consistent hole tolerances across batches. Its robust construction reduces replacement costs and downtime, while the clear go/no-go feedback keeps operators focused on the task at hand and ensures reliable results every shift.
