A workshop measurement tool designed for verifying internal metric threads with repeatable results. The DAISHUJIE Thread Ring Gauge Set combines hardened measuring surfaces with simple operation to reduce uncertainty during inspections. Is it the right gauge for M21–M24 fine-thread work?
⚡ At a Glance
- • Measurement Accuracy: Precise thread-fit checking using GO and NOGO rings for clear pass/fail assessment
- • Best for: Workshop technicians, machinists and quality inspectors verifying internal metric threads
- • Not ideal for: Applications requiring external thread measurement or integrated digital readouts
Used to test internal thread size to confirm parts sit within tolerance. Hardened measuring surfaces improve wear resistance and extend service life.
Clear Go/NoGo Decisions – thanks to GO and NOGO ring pair
GO and NOGO rings present clear limits for acceptable internal threads, letting the gauge confirm whether a bore meets tolerance by either passing or stopping. The set format supports quick visual and tactile verification without complex setup.
Rapid pass/fail checks speed up inspection and reduce rework, useful for batch checks or final QA. Minimal training required to perform consistent assessments.
Durable Measuring Surfaces – with high-quality steel and hardening
High-quality steel and hardened measuring surfaces resist wear from repeated contact, preserving dimensional reliability over time. Wear resistance maintains gauge accuracy through prolonged shop use.
Reduced need for frequent replacement or recalibration keeps downtime low. Long service life supports ongoing production and inspection routines.
Suitable for Fine-Thread Sizes – thanks to metric fine-tooth coverage
Coverage tailored to fine-pitch metric threads in the M21–M24 range, with multiple pitch sizes indicated in the product name for compatibility. The 6g tolerance class and fine-tooth design align with typical fine-thread requirements.
Direct compatibility with common fine-thread components avoids improvised checking methods. Ideal for parts where precise internal thread fit is critical.
