Aero-derivative fasteners exceed the safety-critical needs of the aviation and aerospace industries.

These high-precision components are resistant to extreme temperatures, pressure variations, chemical corrosion and vibration while maintaining superior tensile and shear strength.

Lightweight construction. High-performance characteristics

Assembly and application challenges within the gas turbine industries are notoriously complex. Here, our customers require precision-engineered, high-performance, approved and accredited components that reduce weight, improve aerodynamic performance, can operate in harsh environments, are self-sealing and are able to resist high corrosion and oxidation. Because of these varied yet safety-critical demands, a meticulous approach to design, tooling, material selection and fastening techniques is required throughout every project.

At the LoneStar Group, our global teams can offer the gas turbine sector deep technical understanding, unmatched manufacturing capability and proven long-term expertise in delivering aero-derivative fasteners of the highest quality.

Our teams can offer aero-derivative fasteners for when historic or legacy drawings call for specific standards that are no longer necessary due to the industrialised nature of the application. We can collaborate directly with your engineers to assist the redesign of industrialised fasteners to include tight tolerances, special testing or coating requirements through new part/drawing integration, reverse engineered modelling, deviation permits or new part qualification.  

Our aero-derivative fastener types include, but are not limited to: 

  • 12-point bolts
  • 12-point lock nuts 
  • Hex bolts/nuts
  • Studs 
  • Tie bolts 
  • Safety-critical tension bolts 

We have longstanding experience in working with many varied exotic materials including, but not limited to:

  • Waspaloy to AMS 5706, AMS 5707, AMS 5708 and AMS 5709
  • Alloy 718 to AMS 5662 and AMS 5663
  • Alloy 80A to BS HR601 
  • Alloy 901 to AMS 5660, AMS 5661, BS HR55
  • Alloy 90 to BS 3 HR2 
  • RENE 41 to AMS 5713
  • ASTM A453 grade 660 class A, B, C and D

Supported by our on-site, independent ISO 17025 UKAS materials and fastener testing laboratories, all fasteners are delivered with increased peace of mind and full certification packs.
