Hex Nuts

Hayn Hex Nuts are 18-8 stainless steel end fitting nuts for Concealed Thread and Traditional Cable Rail systems, available in both right and left hand thread across four sizes from 10-32 through 3/8-24 — one of the broadest thread hand combinations in the Hayn nut lineup. 

Strong Where It Matters

Hex Nuts

The availability of both right and left hand thread in every size is the key feature here, allowing the hex nut to be matched correctly to the thread hand of the termination stud or tensioner it seats against regardless of position in the run. Eight configurations cover thread sizes from 10-32 through 3/8-24 in paired RH and LH options, making it straightforward to specify the correct nut for both the tensioning and fixed ends of any Hayn cable rail assembly. For locking versions that resist backing off under thermal cycling, see the Hayn Hex Lock Nuts with Nylon Insert.

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.
