About Skybolt Fasteners

Precision-Engineered Quarter-Turn Fasteners for Aerospace, Defense, and High-Performance Applications

Skybolt manufactures high-strength panel fasteners, quick-release fasteners, and captive fastener systems in 300-series stainless steel and proprietary Skytanium® alloys. Our products serve general aviation, commercial aerospace, defense, industrial, and marine markets with design strength ratings that meet or exceed NASM5591 Chart II specifications.

Product Innovations

  • Skytanium® Alloy – 30–50% weight reduction with steel-equivalent strength properties
  • Diamondhead® CLoc® Rc – 27 stainless fasteners meet NASM5591 Chart II ratings (independently tested)
  • Adjustable-Depth Fasteners – Accommodates varying panel stack-ups
  • Specialty Head Styles – Wing, folding ring, and folding wing configurations
  • Nutsert-Installed Systems – Blind installation for limited-access applications
  • Quad-Lead Skyloc® – Positive-locking structural fastening

Quarter-Turn Fastener Systems

Skybolt produces fastener families compatible with industry-standard Camloc®, Dzus®, and Airloc® designs:

  • CLoc® Series – Camloc®-style quarter-turn fasteners (most common in general aviation and commercial aerospace)
  • DLoc® Series – Dzus®-style spring-loaded fasteners
  • ALoc® Series – Airloc®-style fasteners (common on Beechcraft applications)

Most Skybolt quarter-turn fasteners use 300-series stainless steel, avoiding the corrosion susceptibility of A286 or 400-series alloys while maintaining superior strength-to-weight performance.
