#9016 Type III Square Penetration Gages
The #9016 Type III Square Penetration Gage is a precision inspection instrument designed to measure recess penetration depth in Type III square drive head screws.
Manufactured in accordance with ASME B18.6.3 and B18.6.5M standards, the 9016 Series verifies proper square recess depth and geometry conformity for production and quality control environments.
Square drive recesses require accurate penetration depth control to ensure proper driver engagement, torque transmission, and assembly reliability.
The 9016 Series uses a dial indicator based measurement system to determine recess penetration depth relative to the screw head surface.
Available drive sizes:
9016-00 – Size 00
9016-0 – Size 0
9016-1 – Size 1
9016-2 – Size 2
9016-3 – Size 3
9016-4 – Size 4
When ordering, specify:
• Inch or metric dial indicator
• Optional SPC compatible digital indicator
The 9016 Series is ideal for:
• Fastener manufacturers
• Construction fastener producers
• Industrial hardware suppliers
• Quality inspection laboratories
• OEM assembly operations
Gage probes are heat treated, thermally stabilized, and surface treated to provide additional wear resistance and extended gage life.
Long form calibration certificates provide dimensional verification and traceability to the National Institute of Standards and Technology, NIST.
The 9016 Series ensures reliable square recess penetration verification in compliance with ASME standards.
