#9003 Type 1 Test Block Gage
The #9003 Type 1 Test Block Gage is a precision master reference tool designed to verify dimensional accuracy of Phillips Type I and Type Z driver bits and screwdrivers.
Manufactured in compliance with ANSI B107.600 and ASME B18.6.4 / B18.6.5M standards, the 9003 Series serves as a calibrated master reference for driver tool inspection systems.
Unlike ring gages, which provide GO / NO-GO verification, the 9003 Test Block provides a controlled dimensional reference cavity used to evaluate:
• Driver bit geometry
• Tip dimensional conformity
• Wear conditions
• Calibration verification of ring gages
The precision machined recess cavity is manufactured to specified tolerances and serves as a benchmark reference in production and laboratory environments.
Available recess sizes:
9003-00 – Size 0
9003-01 – Size 1
9003-02 – Size 2
9003-03 – Size 3
9003-04 – Size 4
The 9003 Series is ideal for:
• Driver bit manufacturers
• Screwdriver manufacturers
• Calibration laboratories
• Incoming inspection programs
• Quality control departments
Each test block is heat treated, thermally stabilized, and surface treated to provide additional wear resistance and dimensional stability.
Long form calibration certificates provide dimensional verification and traceability to the National Institute of Standards and Technology, NIST.
The 9003 Series delivers stable, repeatable master reference verification for cross recess driver systems.
