#9001 Type 1 Plug Gage

The #9001 Type 1 Plug Gage is a precision inspection tool designed to verify internal cross recess dimensional conformity in Phillips Type I and Type Z head screws.

Manufactured in accordance with ANSI B107.600 and ASME B18.6.4 / B18.6.5M standards, the 9001 Series provides functional size verification of cross recess geometry.

This gage verifies:

• Proper cross recess dimensional form

• Correct driver size compatibility

• Compliance with referenced standards

• Production consistency

Unlike penetration gages, the 9001 Series is a plug-style gage that verifies recess size and form through controlled engagement.

Available recess sizes:

9001-00 – Size 0

9001-01 – Size 1

9001-02 – Size 2

9001-03 – Size 3

9001-04 – Size 4

The hardened precision ground plug profile ensures accurate inspection of cross recess head screws used in:

• Machine screws

• Sheet metal screws

• International production programs

• Quality lab inspection

All plug gages are heat treated, thermally stabilized, and surface treated to maximize wear resistance and extend gage life.

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

The 9001 Series delivers reliable and repeatable cross recess size verification for production and laboratory environments.
