Eye Jaw Toggles

Hayn Eye Jaw Toggles are Type 316 stainless steel articulating fittings that combine a fixed eye on one end with a clevis jaw on the other, providing angular freedom at the jaw while connecting cleanly to a bolt or pin at the eye. 

Strong Where It Matters

Eye Jaw Toggle

The eye jaw configuration is a common choice where one end of the toggle connects to a fixed chainplate bolt and the other needs to pivot freely to accommodate rig movement. Hardware factor dimensions are published for every size, making it straightforward to calculate the total assembly length accurately during the design or replacement process. Available in eight sizes with pin and hole diameters from 1/4" through 3/4", manufactured from Type 316 stainless steel throughout.

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.
Precision Manufacturing Our Rocky Hill production floor runs CNC vertical mills, CNC lathes, large-capacity mill-turn centers, and waterjet cutting systems — all configured to produce hardware that meets exact specifications, every time.
75+ Years of Excellence Hayn has been engineering and manufacturing marine and architectural rigging hardware since 1950. That track record isn't just history, it's the design knowledge, failure data, and continuous improvement that goes into every product we make.
