Bad Boy Mower 013-5301-00 – 5/8-11 Nylon Insert Jam Locknut Zinc

The Bad Boy Mower 013-5301-00 – 5/8-11 Nylon Insert Jam Locknut Zinc is a genuine OEM fastener engineered for secure, vibration-resistant connections in high-stress mower applications. Designed with a nylon insert and a jam nut profile, this locknut provides consistent clamping force while preventing loosening caused by vibration, impact, or repeated motion.

Manufactured from high-strength steel and finished with a protective zinc coating, the 013-5301-00 offers long-lasting durability and superior corrosion resistance. The nylon insert provides a tight, self-locking grip on mating threads, while the jam nut’s low-profile design makes it ideal for limited-clearance or double-nut applications.

This OEM 5/8-11 locknut is used throughout various Bad Boy Mower assemblies, including wheel hubs, suspension components, and pivot points. It maintains secure fastening even under heavy torque, ensuring safe, reliable operation in all mowing conditions.

Aftermarket alternatives often use inferior nylon or non-hardened steel, leading to premature loosening and wear. The Bad Boy OEM 013-5301-00 Nylon Insert Jam Locknut guarantees precise threading, high tensile strength, and OEM-grade reliability—ensuring your mower performs safely and efficiently season after season.
