#9012 Type II Plug Gages

The #9012 Type II Plug Gage is a precision dimensional inspection tool designed to verify recess size conformity for Type II Frearson cross recess head screws.

Manufactured in compliance with ANSI B107.600 and ASME B18.6.4 / B18.6.5M standards, the 9012 Series provides accurate verification of Frearson cross recess geometry and dimensional limits.

Frearson drive geometry differs from Phillips and Pozidriv designs and requires dedicated inspection tooling to ensure proper dimensional conformity.

Unlike penetration gages, which measure depth, the 9012 Plug Gage verifies the dimensional form and size of the screw recess cavity.

This gage confirms:

• Proper recess geometry

• Dimensional conformity to applicable standards

• Manufacturing consistency

• Production quality control

Available recess sizes:

9012-00 – Size 0

9012-01 – Size 1

9012-02 – Size 2

9012-03 – Size 3

9012-04 – Size 4

The 9012 Series is ideal for:

• Marine fastener manufacturers

• Aerospace suppliers• Defense contractors

• Automotive production

• Quality inspection laboratories

Each plug gage is heat treated, thermally stabilized, and surface treated to maximize wear resistance and dimensional stability.

Long form calibration certificates provide dimensional verification and traceability to the National Institute of Standards and Technology, NIST.

The 9012 Series delivers reliable dimensional verification for Type II Frearson cross recess inspection systems.
