Washer – Fender

Hayn Fender Washers are 18-8 stainless steel large-diameter washers for Traditional Cable Rail termination hardware, available in four nominal sizes from 1/4" through 1/2" to distribute bearing load across a broader post face surface at the termination point. 

Strong Where It Matters

Washer - Fender

The fender washer's oversized outside diameter relative to its hole size spreads the clamping force of the nut or fitting across a wider area of the post face, preventing the hardware from pulling into or marking the post material under cable tension — particularly useful on wood post installations where point loading at a standard washer footprint can damage the surface over time. Available in nominal sizes of 1/4", 5/16", 3/8", and 1/2" to match the thread sizes used across the Hayn Traditional cable rail termination stud and hex nut range. Manufactured from 18-8 stainless steel for corrosion resistance in exterior architectural applications.

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.
