TXP – 6 Lobe Plus Handheld Inspection Gages

Precision penetration, GO / NO-GO, tamper resistant, and final inspection gages for TXP 6-lobe plus drive systems.

Universal Fastener Gages manufactures a complete line of handheld TXP 6-lobe plus inspection gages engineered for enhanced torque engagement verification, recess depth validation, and objective pass / fail inspection. Designed for high-performance fastener applications, TXP handheld gages provide repeatable, production-ready inspection without the need for bench systems.

What Is TXP 6-Lobe Plus?

TXP 6-lobe plus drive systems are engineered to provide improved torque transfer, reduced stress concentration, and enhanced driver engagement compared to standard 6-lobe systems.

TXP handheld gages are used to verify:

  • Recess penetration depth
  • Functional engagement geometry
  • GO / NO-GO dimensional compliance
  • Tamper resistant center pin integrity
  • Driver bit wear and compatibility

These gages are commonly used in aerospace, automotive, medical device, and industrial fastener manufacturing environments.

Inspection Types Explained

  • Penetration – Confirms recess depth meets design requirements and supports proper driver engagement.
  • GO Inspection – Verifies minimum acceptable geometry for torque transmission.
  • NO-GO Inspection – Detects excessive wear, over-machining, or nonconforming recess dimensions.
  • Fallaway – Confirms proper disengagement characteristics in applicable systems.
  • Tamper Resistant Verification – Ensures center pin and security features meet specification.

Applications

  • Aerospace structural fasteners
  • Automotive powertrain components
  • Medical implant and instrument fasteners
  • Defense and high-reliability systems
  • Industrial torque-critical assemblies

TXP systems are frequently specified where higher torque transmission and enhanced engagement performance are required.
