The #9035 Metric Spline Penetration Gage is a precision inspection instrument designed to verify internal spline socket depth and functional driver engagement in metric spline socket cap screws, shoulder screws, and set screws.

Manufactured in accordance with ASME/ANSI B18.3.1M and 6M standards, the 9035 Series confirms that internal spline recess depth meets specified penetration and engagement requirements to ensure proper torque transfer and prevent driver disengagement.

Designed for manufacturing, quality control, and incoming inspection environments, this gage verifies:

• Minimum spline 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 spline probe is calibrated to specified metric dimensions and tolerances and is traceable to the National Institute of Standards and Technology (NIST).

Ideal for:

• Metric spline fastener manufacturing• Automotive and aerospace metric programs• International production facilities• ISO-compliant quality systems• High-volume manufacturing validation

The 9035 Series provides repeatable, production-ready metric spline penetration verification.
