Description
JBO Thread Plug Gauge is a precision Go/No-Go tool designed specifically for metric coarse threads. This right-hand gauge covers M4 x 0.7 with 4H tolerance, giving you a quick and reliable check for threaded holes in machined parts, fixtures, and assemblies. Built for durability, it’s crafted from hardened steel to withstand routine use in shop environments and deliver consistent results over time.
- Go/No-Go efficiency: The dual-function design lets you quickly determine acceptance or rejection of a hole in a single pass, speeding up QA checks and reducing guesswork.
- Metric coarse thread compatibility: Precisely sized for M4 x 0.7 coarse threads, ensuring reliable fit verification across standard holes and components.
- Hardened steel construction: Rugged material resists wear, maintains accuracy, and delivers long service life in demanding workshop conditions.
Using the JBO Thread Plug Gauge helps technicians and engineers confirm hole readiness, streamline inspection workflows, and maintain consistent joint quality. By catching out-of-tolerance threads early, it reduces rework, minimizes downtime, and supports dependable assembly across projects.
