#9075 Metric Hexagon GO-NOGO Gage
The #9075 Metric Hexagon GO-NOGO Gage is a precision production inspection tool designed to verify internal metric hex recess size and functional driver fit in metric socket head cap screws, shoulder screws, set screws, and hex keys.
Manufactured in accordance with ASME/ANSI B18.3.1M standards, the 9075 Series provides rapid functional size verification using precision ground GO and NO-GO plug ends.
This gage confirms:
• Acceptable internal metric hex recess size• Proper hex key engagement• Compliance with ASME B18.3.1M tolerances• Production line quality control
The GO end verifies minimum functional engagement.The NO-GO end confirms the recess does not exceed maximum allowable size limits.
Designed for high-volume metric manufacturing environments, the 9075 Series enables fast, repeatable inspection without indicator measurement equipment.
Ideal for:
• Metric socket head cap screw manufacturing• International automotive and aerospace programs• ISO-certified production systems• In-process production control
Each gage is heat treated, thermally stabilized, and surface treated for maximum wear resistance. All gage probes are calibrated to specified metric dimensions and tolerances and are traceable to the National Institute of Standards and Technology (NIST).
The 9075 Series delivers dependable, production-ready metric hex recess verification.

2) Inspection Function
The 9075 Series provides functional size verification:
GO End• Confirms minimum acceptable recess size• Ensures proper metric hex key engagement
NO-GO End• Confirms recess does not exceed maximum tolerance• Prevents oversize condition
This gage verifies recess size and form compliance, not penetration depth.
3) Materials & Construction
Universal’s 9075 Series gages feature:
• Hardened precision ground metric hex plug ends• Thermally stabilized tool steel• Surface-treated wear-resistant finish• Clearly marked GO and NO-GO ends• Production-durable design
Designed for repeated use in high-volume metric manufacturing environments.
4) Ordering Information
When ordering, specify:
• Metric hex size• Certification package if required
All gage probes are calibrated to specified metric dimensions and tolerances and are traceable to NIST standards.
