Mount Screws – Socket Head Cap Screw

Hayn Socket Head Cap Screws are stainless steel 3/8-16 UNC mount screws available in 2" and 3" lengths for use in Green Wall System installations and in conjunction with the Hayn Threaded Stud and Hex Nut System. 

Strong Where It Matters

Hex Nuts

The socket head cap screw profile keeps the fastener head low and tool-accessible in tight mounting situations where a standard hex head screw would require clearance for a wrench. The 2" length suits standard mounting depths, while the 3" length accommodates thicker structural members or applications where additional thread engagement is required. Compatible with the Hayn Threaded Stud and Hex Nut System for installations that combine Green Wall and Traditional cable rail hardware on the same structure.

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. 
  • Type 316 stainless steel construction for superior saltwater corrosion resistance
  • Manufactured in Rocky Hill, Connecticut to Hayn's proprietary tolerances
  • Precision-machined using advanced CNC manufacturing equipment



  • Engineered for seamless integration in marine and architectural rigging systems

  • Short lead times on both standard and custom components

  • Backed by 75 years of marine and architectural hardware expertise
