Hayn Thimbles

Hayn Thimbles are Type 316 stainless steel wire rope inserts that protect the wire loop at eye splices and compressed sleeve terminations from deformation and abrasion at the connection point. 

Strong Where It Matters

Swage Shroud Terminals

A thimble is a simple but functionally important component — without it, the wire at a loop termination bears directly against the shackle pin or fitting it connects to, which flattens the wire strands and accelerates fatigue failure at that point over time. The grooved profile keeps the wire loop correctly shaped under load and distributes the bearing stress evenly across the contact surface. Available in nine standard duty sizes covering wire diameters from 3/32" through 1/2", manufactured from Type 316 stainless steel for long-term corrosion resistance in saltwater environments.

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.
