NAVTEC BY HAYN

The NAVTEC N690 Rod Turnbuckle Assembly is a complete Type 316 stainless steel jaw-to-jaw rod turnbuckle available across 15 configurations covering rod sizes from -04 through -60, providing a ready-to-install tension adjustment assembly for NAVTEC rod rigging systems.

NAVTEC by Hayn - Strong Where It Matters

NAVTEC N690 Rod Turnbuckle Assembly

The N690 ships as a complete assembly with jaw ends on both sides of the turnbuckle body, eliminating the need to source and match the stud, body, and jaw components separately. Open lengths run from 12-1/8" on the -04 rod size through 37-3/16" on the -60, with closed lengths and full jaw geometry dimensions published for all 15 configurations to simplify assembly length calculations during design and replacement. Manufactured from Type 316 stainless steel throughout, with thread sizes from 3/8-24 through 1-1/4-12 matching the corresponding NAVTEC rod sizes across the full range.

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.
