Eye Bolt

Hayn Eye Bolts are stainless steel threaded eye fittings for Traditional Cable Rail Toggle Jaw systems, available in eight configurations with shank lengths from 7/8" through 6-1/4" and thread sizes of 1/4", 5/16", and 3/8" to accommodate varying post thicknesses and structural attachment requirements. 

Strong Where It Matters

Eye Bolt

The eye bolt provides the fixed attachment point that the toggle jaw assembly connects to at the post or structural member, and selecting the correct shank length is essential — the shank must be long enough to pass fully through the post material with sufficient thread engagement on the far side. Three thread sizes cover the standard toggle jaw hardware range, with short, medium, and long shank options on the 1/4" and 3/8" thread sizes to accommodate post thicknesses from under 1" through 6" and eye sizes from 3/8" through 1" depending on the configuration. Manufactured from stainless steel for long-term corrosion resistance in exterior architectural 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.
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.
