#9030 Spline Penetration Gage
The #9030 Spline Penetration Gage is a precision inspection instrument designed to verify internal spline socket depth and functional driver engagement in spline socket cap, shoulder, and set screws.
Manufactured in accordance with ASME/ANSI B18.3 standards, the 9030 Series confirms that internal spline recess depth meets specified penetration and engagement requirements to ensure proper torque transfer and prevent driver disengagement or stripping.
Designed for manufacturing, quality control, and incoming inspection environments, this gage verifies:
• Minimum spline 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 spline probe is calibrated to specified dimensions and tolerances and is traceable to the National Institute of Standards and Technology (NIST).
Ideal for:
• Spline socket cap screw manufacturing• Shoulder and set screw production• Automotive and aerospace spline fasteners• ISO-compliant quality systems• High-volume manufacturing validation
The 9030 Series provides repeatable, production-ready spline penetration verification.
