#9052 12-Point Penetration Gage

The #9052 12-Point Penetration Gage is a precision inspection instrument designed to verify internal multipoint recess depth and functional driver engagement in 12-point socket profile head screws.

Manufactured in accordance with DIN 34824 and VW 01043 standards, the 9052 Series confirms that the internal 12-point recess 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 12-point recess penetration depth• Proper driver engagement geometry• Functional torque transmission capability• Production and receiving inspection compliance

The 9052 Series is ideal for automotive, European OEM, and high-performance fastener applications where multipoint drive systems are used.

Available with inch or metric dial indicators, with optional SPC-compatible digital indicators upon request.

Each probe is calibrated to specified dimensions and tolerances and is traceable to the National Institute of Standards and Technology (NIST).

The 9052 Series provides repeatable, production-ready 12-point penetration verification.
