Description:
The 06500813 nylon flange lock nut is a genuine OEM Ariens / Gravely fastener designed to provide secure, vibration-resistant fastening in a wide range of mower, blower, bagger, and attachment assemblies. This nut features a 1/4-20 thread, an integrated flange for load distribution, and a nylon locking insert that resists loosening under vibration and repeated operation.
Manufactured from grade fastener steel and finished with zinc corrosion coating (ZCC), this nut is engineered for durability and long service life in demanding outdoor power equipment environments. The flange design eliminates the need for a separate washer while protecting mounting surfaces and maintaining proper torque.
The Ariens / Gravely 06500813 lock nut is commonly used in blower housings, impeller assemblies, fuel systems, electrical mounts, steering controls, deck lift systems, frames, and seat latch assemblies across residential and commercial platforms.
