Dome Nut – No Through Hole

 Hayn Dome Nuts (No Through Hole) are Type 316 stainless steel caps that thread onto Concealed Thread Termination Stud hardware at the end vertical or post, providing a clean, finished appearance at the cable termination point in two thread configurations. 

Strong Where It Matters

Dome Nut – No Through Hole

The dome profile covers the exposed stud thread completely without a wire pass-through hole, making this the correct nut for fixed termination ends where the cable does not continue through the post to the other side. Available in 1/4-28 right hand thread (9/16" outside diameter) and 5/16-24 right hand thread (3/4" outside diameter), both compatible with the Hayn Threaded Termination Stud system for wire up to 1/4". For installations where the cable passes through the post and requires a nut with a wire clearance hole, see the Dome Nut With Through Hole.

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.
