#9017 Type III Square Plug Gages

The #9017 Type III Square Plug Gage is a precision dimensional inspection tool designed to verify square recess geometry in Type III square drive head screws.

Manufactured in accordance with ASME B18.6.3 and B18.6.5M standards, the 9017 Series provides accurate recess conformity verification for production and quality control environments.

Square recess fasteners require tightly controlled dimensional accuracy to ensure proper driver engagement, torque transfer, and assembly reliability.

The 9017 Series plug gages verify:

• Recess width

• Recess geometry conformity

• Dimensional tolerance compliance

• Manufacturing consistency

Available recess sizes:

9017-00 – Size 00

9017-0 – Size 0

9017-1 – Size 1

9017-2 – Size 2

9017-3 – Size 3

9017-4 – Size 4

Each plug gage is precision ground to conform to applicable ASME dimensional requirements.

The 9017 Series is ideal for:

• Fastener manufacturers

• Construction hardware suppliers

• Industrial fastener producers

• OEM assembly operations

• Quality inspection laboratories

Plug gages are heat treated, thermally stabilized, and surface treated to provide additional wear resistance and maximize gage life.

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

The 9017 Series ensures reliable dimensional inspection of Type III square recess screws in compliance with ASME standards.
