Engineered for rapid assembly where tools are impractical
Our 304 Stainless Steel Wing Nuts combine marine-grade corrosion resistance with ergonomic hand-tightening capability. Featuring precision-cast wings and ISO-compliant threading, they deliver secure fastening in marine, chemical processing, and outdoor installations where conventional tools can't be used.
Industrial-Grade Hand-Tightening Performance
Crafted from certified 304 stainless steel (AISI 18/8), these wing nuts solve critical challenges in maintenance-heavy environments. The oversized wings provide 35% more torque leverage than standard thumb nuts, while the radiused base prevents flange damage on sensitive surfaces.
