NAVTEC C651 Tip Turnbuckle Assembly

The NAVTEC C651 Tip Turnbuckle Assembly pairs a chrome-plated bronze body with a high-strength Nitronic 50 ball head screw and stainless steel nose, providing the precision tension adjustment and material performance that NAVTEC rod rigging demands. 

NAVTEC by Hayn - Strong Where It Matters

NAVTEC C651 Tip Turnbuckle Assembly

The Nitronic 50 ball head screw is the key material choice here — the same high-strength, corrosion-resistant alloy used in NAVTEC rod rigging itself, ensuring compatibility and long-term performance at the most load-critical point in the tensioning assembly. On -30 rod size and larger, the body transitions to stainless steel with a bronze nose, reflecting the higher loads those sizes carry. Available in 12 configurations covering NAVTEC rod sizes from -04 through -60, with thread sizes from 5/16-24 through 1.0-12 and open lengths from 6-3/4" through 16-1/8" to suit the full range of NAVTEC rod rigging applications.

Engineered In America Every Hayn fitting is designed and manufactured at our facility in Rocky Hill, Connecticut — the same American workmanship that has set the standard for stainless steel rigging hardware since 1950.
Cold-Worked Production Hayn fittings are cold-worked, not cast. That distinction matters: the cold-working process refines grain structure, increases fatigue resistance, and produces a fundamentally stronger component — one built to perform when the load comes on it.
NAVTEC ENGINEERING STANDARDS NAVTEC components are engineered to perform under the exact conditions that demand the most from your rigging — offshore passages, high-load racing applications, and everything in between. Every fitting is precision-machined to tight tolerances, built from high-grade stainless steel, and designed to integrate seamlessly into rod rigging systems where failure is not an option. 
YOUR EXCLUSIVE SOURCE FOR NAVTEC Hayn is the sole authorized manufacturer and supplier of NAVTEC rigging components. That means every part you order is made to the original specifications, backed by Hayn's manufacturing expertise, and supported by our team in Rocky Hill. There is no other legitimate source for new NAVTEC product — what you get here is the real thing. 
  • Type 316 stainless steel construction for superior saltwater corrosion resistance
  • Manufactured in Rocky Hill, Connecticut to Hayn's proprietary tolerances
  • Precision-machined using advanced CNC manufacturing equipment



  • Engineered for seamless integration in marine and architectural rigging systems

  • Short lead times on both standard and custom components

  • Backed by 75 years of marine and architectural hardware expertise
