One New Aftermarket Replacement 1/2-Inch Flange Nut for Snapper, Simplicity, and Murray Lawn and Garden Equipment
This aftermarket replacement 1/2-inch flange nut is a Grade 5 zinc-plated steel fastener used as a standard hardware component across a wide range of Snapper, Simplicity, and Murray outdoor power equipment. The built-in flange distributes clamping load evenly, reducing the need for a separate washer and providing a secure, vibration-resistant connection. Grade 5 (GR5) construction meets SAE strength specifications, and the zinc plating (ZP) provides corrosion resistance for use on mower decks, frames, engine mounting, and other equipment assemblies.
