Spi 34-522-3 Threaded Ring Gage M33 X 2.00 Metric Class 6G

Product Description

The SPI 34-522-3 is a No Go threaded ring gage used to verify external metric thread dimensions on machined parts. Manufactured from Oil Hardened Non-Shrinking Steel (OHNS), this single-ring gage checks M33 x 2.00 metric threads to Class 6G tolerance. A No Go gage confirms that a threaded workpiece does not exceed the maximum material condition, meaning the part should not pass through the gage. An NPL Traceability Certification is included with each unit, supporting documented quality control processes. This gage is used in production inspection, incoming inspection, and machine shop environments by machinists, quality technicians, and inspection personnel.

The SPI 34-522-3 is suited for inspecting externally threaded components machined to M33 x 2.00 metric specifications at Class 6G tolerance. Class 6G is the standard tolerance class for general-purpose metric fasteners and threaded components. This gage is appropriate for use in manufacturing, toolroom, and quality assurance settings where metric thread verification is required. The included NPL traceability documentation supports ISO and AS9100 quality system requirements.

Key Features

• No Go ring gage rejects parts that exceed maximum material condition for M33 x 2.00 metric threads
• Class 6G tolerance classification for general-purpose metric thread inspection
• Oil Hardened Non-Shrinking Steel (OHNS) construction for wear resistance and dimensional stability
• NPL Traceability Certification included for quality system compliance
• Single-ring design for straightforward No Go inspection workflow

Compatibility

Designed for inspection of externally threaded workpieces with M33 x 2.00 metric threads manufactured to Class 6G tolerance. Used as a No Go member in a Go/No Go thread inspection process.

Installation Notes

Threaded ring gages are used by quality technicians and machinists and do not require permanent installation. Store the gage in its protective case when not in use to prevent damage to the thread form. Handle with clean, dry hands or inspection gloves to avoid corrosion from skin oils. Calibration intervals should be established per your facility quality plan and applicable inspection standards.
