#9095 Quadrex Penetration Gage – ISOTEC QX Series
The #9095 Quadrex Penetration Gage is a precision inspection tool designed to verify proper driver penetration in Quadrex four-wing recess screws manufactured to ISOTEC QX-001 and QX-002 specifications.
Penetration gages are used to confirm that driver engagement depth meets dimensional requirements without over-penetration or insufficient contact. Proper penetration ensures torque transfer accuracy, minimizes cam-out, and maintains assembly integrity.
Available sizes:
9095-00 – Size 00
9095-0 – Size 0
9095-1 – Size 1
9095-2 – Size 2
9095-3 – Size 3
9095-4 – Size 4
The 9095 Series is ideal for:
• Driver bit manufacturers
• Screw manufacturers
• Aerospace fastener producers
• Automotive assembly operations
• Industrial quality control departments
• Calibration laboratories
Gage probes are heat treated, thermally stabilized, and surface treated to provide additional wear resistance and long-term dimensional stability.
Long form calibration certificates provide certified dimensional values and traceability to the National Institute of Standards and Technology, NIST.
The 9095 Series ensures repeatable Quadrex recess depth verification and inspection consistency.
