Description
Overview:
The M12 x 1.5 Metric Fine Go Ring Gauge 6g - 4129 Series is a precision inspection tool for checking the accuracy of external metric threads on studs, bolts and shafts used across construction and garden machinery. Manufactured from hardened alloy steel for stability and long service life, it verifies that threads conform to the ISO 1502 standard and fall within 6g tolerance limits. Supplied as a matched Go/No-Go ring set within the 4129 Series, it enables quick pass/fail assessment of thread diameter and pitch accuracy without complex setup. Ideal for workshop, production, and maintenance use, it helps ensure reliable assembly and reduces the risk of cross‐threading or premature wear on parts found in equipment such as compactors and mowers.
Key Features:
- M12 x 1.5 Metric Fine size for common external fasteners and shafts
- 6g tolerance class for ISO-compliant inspection of external threads
- Conforms to ISO 1502 for consistent, repeatable measurement results
- Hardened alloy steel construction for wear resistance and dimensional stability
- Supplied as Go and No-Go rings to provide clear pass/fail decisions
- Smooth, accurate gauging to reduce inspection time on the shop floor
- Suitable for routine checks, in-process control and final inspection
- Helps prevent assembly issues, galling, and warranty rework
- Robust build for daily use in demanding workshop and site environments
- Clear size/tolerance markings for easy identification in tool control
Typical Applications:
Checking external threads on bolts, studs, and shafts fitted to construction plant, agricultural and garden machinery. Used in machine shops, maintenance departments, inspection cells, and on-site service vans to validate thread quality before assembly, after repair, or during QA sampling in production runs.
Also known as:
Thread ring gauge, Go/No-Go ring, limit ring gauge, external thread check ring, thread inspection ring, pass/fail ring gauge, acceptance gauge for metric threads.
