#9025 Hexagon Penetration Gage
The #9025 Hexagon Penetration Gage is a precision inspection instrument designed to verify internal hex socket depth and functional driver engagement in socket cap, shoulder, and set screws.
Engineered in accordance with ASME/ANSI B18.3 standards, the 9025 Series confirms that internal hex recess depth meets specified penetration and engagement requirements to ensure proper torque transfer and prevent driver cam-out.
Designed for manufacturing, quality control, and incoming inspection environments, this gage verifies:
• Minimum hex penetration depth• Proper driver engagement geometry• Functional socket conformity• Production and receiving inspection compliance
Available with inch or metric dial indicators, with optional SPC-compatible digital indicators upon request.
Each gage probe is calibrated to specified dimensions and tolerances and is traceable to the National Institute of Standards and Technology (NIST).
Ideal for:
• Socket cap screw manufacturing• Shoulder screw production• Set screw inspection• Automotive and aerospace applications• ISO-compliant quality systems
The 9025 Series provides repeatable, production-ready hex penetration verification.
