FAQ

Will these fit high-pressure Tri-Clamp (Tri-Clover) clamps?

Yes, these bolt sets are designed for high-pressure Tri-Clamp style sanitary clamps. Use the size table above to match bolt length to your clamp size.

Why use a brass nut with a stainless bolt?

Brass helps reduce thread galling against stainless steel, making it easier to tighten and loosen over time, especially with frequent cleanings.

Do these include a lock washer?

Yes. Each set includes a lock washer to help maintain preload under vibration and thermal cycling.

What material is the bolt?

The bolt is 304 stainless steel for corrosion resistance in sanitary processing environments.

Tips to prevent seizing or galling?

Hand-start threads, avoid over-torquing, and consider using a food-grade anti-seize compatible with your process. Clean and dry hardware after washdowns.
