Hi-Lok Pins

AIAP is an authorized distributor of the Hi-Lok fastening system, a proven solution combining the strength of a bolt with the weight efficiency of a rivet. Hi-Lok pins are widely used in airframe assembly and maintenance, meeting strict aerospace requirements for strength, fatigue resistance, and consistency. Our inventory includes HL part numbers and OEM-specific versions for Boeing, Lockheed Martin, and Bombardier programs.

Key Features of Hi-Lok Pins
  • Precision-engineered shank – Delivers consistent hole fit and reliable clamp-up load.
  • Head configurations – Available in flush countersunk or protruding styles to maintain smooth aerodynamic surfaces.
  • High-strength materials – Manufactured in titanium, alloy steel, and stainless steel for optimal strength-to-weight performance.
  • Hex recess installation – Pre-drilled recess at the pin end allows use of a hex tool for secure collar installation.
  • Tight tolerances – Ensure precise alignment and prevent joint play under load.
