Spartan Mower 3/8-16 Hex Flange Nut - Part #413-0020-00

High-Strength Serrated Hardware for Zero-Turn Mowers

Maintain the structural integrity of your machine with the 413-0020-00 Hex Flange Nut. Specifically designed for high-vibration areas, this serrated nut "locks" into place, ensuring your mower components stay tight through the toughest jobs.

Zinc Yellow Finish for Longevity

Standard hardware can't handle the grass moisture and debris typical of commercial mowing. The zinc yellow coating on this OEM part offers a critical layer of defense against oxidation, making future maintenance easier and preventing snapped bolts.

Don't settle for hardware store substitutes. This genuine Spartan 3/8-16 flange nut is the exact specification used on the assembly line, providing the specific torque retention and grip required for Spartan SRT, RT, and RZ series models.
