Applications
Thread plug gauges are essential for inspecting thread dimensions in various industries including automotive manufacturing, aerospace, machining, and electronic processing. They help ensure thread accuracy and improve product quality control.
Usage Precautions
- Avoid touching the working surface with bare hands to prevent rust
- Store properly on tool cabinet tables or wooden backing plates - never on machine tool holders or guide rails
- Regularly inspect for damage, rust, or deformation
- For rust prevention, soak in gasoline, wipe carefully, and apply anti-rust oil
- Never store working surfaces of two gauges together to prevent adhesion
- Clean thoroughly after use and store in dry conditions
