12990084 – Flanged Nylock Nut 5/8-11
The 12990084 Flanged Nylock Nut is a heavy-duty 5/8-11 locking fastener designed to provide secure, vibration-resistant fastening for lawn and garden equipment, commercial mowing equipment, and industrial machinery. This nut combines an integrated flange with a nylon locking insert (Nylock) to ensure consistent clamping force while preventing loosening during operation.
The flanged base distributes load evenly across the mounting surface, eliminating the need for a separate washer, while the nylon insert maintains thread tension under vibration and repeated use. Manufactured to standard fastener specifications, the 12990084 nut ensures proper fitment and reliable performance in demanding outdoor environments.
