#1294 EXTRA (TXP) TAMPER RESISTANT GO NO-GO GAGE
The Universal Punch #1294 EXTRA (TXP) Tamper Resistant GO NO-GO Gage is designed for manufacturing inspection of internal hexalobular Plus (TXP) tamper-resistant drive recess fasteners.
Manufactured in accordance with NIQ-804.1.2 and CIQ-804.1.2 standard references, this precision GO / NO-GO inspection gage provides a fast, accurate, and repeatable method for verifying both minimum and maximum allowable dimensional limits of internal TXP tamper-resistant recesses.
The combined GO and NO-GO configuration enables efficient verification of functional recess geometry during production inspection. This ensures proper driver engagement capability while preventing acceptance of oversized recess conditions that may lead to torque transfer failure, cam-out, or compromised tamper-resistant performance.
Universal Punch gage probes are heat treated, thermally stabilized, and surface treated to provide additional hardness for maximum wear resistance in demanding manufacturing environments. All probe elements are calibrated to specified dimensional tolerances and are directly traceable to the National Institute of Standards and Technology (NIST).
SPC-compatible digital indicator systems are available for integration into statistical process control inspection programs.
