Hi-Lite Collars​

AIAP supplies a full range of Hi-Lite collars engineered to complement Hi-Lite pins for secure, reliable fastening. Designed for high-strength aerospace applications, these collars provide the correct torque control for precise installation and long-term performance. We stock both standard HL part numbers and OEM-specific designs used across commercial and defense programs.

Key Features of Hi-Lite Collars
  • Self-locking design – Provides secure retention without the need for additional locking devices.
  • Controlled break-off feature – Shears at the control groove once proper torque is achieved, ensuring consistent preload.
  • Lightweight material options – Available in aluminum, titanium, or stainless steel to meet diverse structural requirements.
  • Vibration resistance – Maintains clamp load in demanding, high-vibration environments.
  • Pin compatibility – Specifically engineered to be used exclusively with Hi-Lite® pins for reduced-weight fastening systems.
