Description
S04117-01 – SCAG 3/8"-16 Flanged Hex Lock Nut (LKNUT) (Genuine SCAG OEM Lock Nut)
The SCAG S04117-01 Flanged Hex Lock Nut is a genuine OEM replacement 3/8"-16 nylon insert lock nut engineered to securely fasten critical components on compatible SCAG commercial lawn mowers. Featuring an integrated flange and nylon locking insert (ELAS), this heavy-duty lock nut provides superior resistance to vibration and loosening, making it ideal for high-stress mower applications.
Manufactured from heat-treated steel with a corrosion-resistant zinc finish, the S04117-01 Lock Nut delivers dependable clamping force while protecting against rust, moisture, and harsh outdoor operating conditions. Its flanged design distributes the load evenly, reducing the need for a separate washer and helping prevent damage to mounting surfaces.
