#9040 Metric Hexagon Penetration Gage
The #9040 Metric Hexagon Penetration Gage is a precision inspection instrument designed to verify internal hex socket depth and functional driver engagement in metric socket head cap screws, shoulder screws, and set screws.
Manufactured in accordance with ASME/ANSI B18.3.6M and compatible with ISO, DIN, JIS, BS, and GB standards, the 9040 Series confirms that internal hex recess depth meets specified penetration and engagement requirements to ensure proper torque transfer and prevent driver cam-out or stripping.
Designed for manufacturing, quality control, and incoming inspection environments, this gage verifies:
• Minimum hex socket penetration depth• Proper driver engagement geometry• Functional socket conformity• Metric production and receiving inspection compliance
Available with inch or metric dial indicators, with optional SPC-compatible digital indicators upon request.
Each hex probe is calibrated to specified metric dimensions and tolerances and is traceable to the National Institute of Standards and Technology (NIST).
Ideal for:
• Metric socket head cap screw manufacturing• Global automotive and aerospace programs• ISO-certified production environments• International fastener suppliers• High-volume manufacturing validation
The 9040 Series provides repeatable, production-ready metric hex socket penetration verification.
