Clevis Pins

Hayn Clevis Pins are CNC-machined Type 316 stainless steel pins covering one of the broadest size ranges available, from 3/16" through 1-3/8" diameter, for use across the full range of Hayn toggle, adjuster, and rigging hardware. 

Strong Where It Matters

Clevis Pins

CNC machining ensures consistent dimensional tolerances across the entire range, which matters when a clevis pin is the load-bearing connection point in a toggle jaw or adjuster fitting. Designated replacement pins are available for Hayn toggle jaws in every standard size from 3/16" through 1-3/8", making it straightforward to source the correct pin for a specific fitting rather than searching for a generic substitute. Additional sizes beyond the standard range are available on request.

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
