Description
When you're putting deck spindles back together or securing blades on your mower, you need fasteners that'll stay tight through all the vibration and bouncing around. Regular nuts have a nasty habit of backing off just when you need them most. This nylon flange nut solves that problem with its built-in nylon insert that grips the bolt threads and a wide flange base that distributes the load.
What You're Getting
- Self-locking nylon insert prevents the nut from vibrating loose during operation
- Wide flange base spreads clamping force over a larger area for better hold
- 5/16" thread size fits common bolts on mower decks and agricultural equipment
- Zinc-plated steel construction resists corrosion from grass moisture and weather
Built for Real Farm Work
This handy fastener is perfect for mower deck assemblies, blade attachments, and other spots where you need a secure connection that won't shake loose. Whether you're working on a zero-turn mower, finishing mower, or rotary cutter, this is the type of hardware that keeps your equipment running reliably season after season.
Made to Last
The steel construction handles the stress of high-speed rotating equipment, while the zinc plating fights off rust from wet grass and morning dew. The nylon locking feature stays effective through repeated removal and installation, though it's always smart to replace lock nuts when they start feeling loose.
Good to Know
These install just like regular nuts but with a bit more resistance when the threads engage the nylon insert - that's normal and means it's working. Don't overtighten them; the nylon does the holding, not extra torque. Keep a few spares in your toolbox since they're one of those parts that always seem to disappear when you need them most.
