#9008 Type IA GO / NO-GO Ring Gage

The #9008 Type IA GO / NO-GO Ring Gage is a precision inspection tool designed to verify dimensional accuracy of Pozidriv, Type IA, and Type Z driver bits and screwdrivers.

Manufactured in compliance with ANSI B107.600 and ASME B18.6.4 / B18.6.5M standards, the 9008 Series provides functional GO and NO-GO verification for cross recess driver tools.

This ring gage ensures:

• Proper driver bit dimensional form

• Correct tip geometry

• Compliance with referenced standards

• Production tool consistency

Unlike plug gages and penetration gages, which inspect screw recesses, the 9008 Series verifies the driver tool itself.

Each ring gage includes precision ground GO and NO-GO openings to confirm driver conformity within allowable dimensional tolerances.

Available recess sizes:

9008-00 – Size 0

9008-01 – Size 1

9008-02 – Size 2

9008-03 – Size 3

9008-04 – Size 4

The GO opening verifies acceptable minimum dimensional conformity.The NO-GO opening confirms the driver does not exceed maximum allowable tolerance.

The 9008 Series is ideal for:

• Driver bit manufacturers

• Screwdriver manufacturers

• Tool calibration laboratories

• Incoming inspection programs

• Quality control departments

All ring 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 9008 Series delivers reliable GO / NO-GO verification for Pozidriv and Type IA driver tools.
