#9076 Metric Hexagon GO-NOGO Gage – ISO 23429

The #9076 Metric Hexagon GO-NOGO Gage is a precision production inspection tool designed to verify internal metric hex recess size and functional engagement in accordance with ISO 23429 and international fastener standards.

Engineered for use with socket head cap screws, shoulder screws, set screws, and hex keys manufactured to ISO, DIN, JIS, BS, and GB standards, the 9076 Series provides rapid GO / NO-GO size verification for metric hex recesses.

This gage confirms:

• Proper internal hex recess size• Compliance with ISO 23429 tolerances• Functional driver engagement• International production quality requirements

The GO end verifies the minimum acceptable recess size to ensure proper hex key engagement.

The NO-GO end confirms the recess does not exceed maximum allowable tolerance limits.

Designed for global manufacturing environments, the 9076 Series provides fast, repeatable inspection without dial indicators or measurement equipment.

Each gage is heat treated, thermally stabilized, and surface treated to maximize wear resistance and long service life. All gage probes are calibrated to specified metric dimensions and tolerances and are traceable to the National Institute of Standards and Technology, NIST.

The 9076 Series is ideal for international metric production control programs requiring ISO compliance.
