539110800 - NUT 3/4-16 HEX TOP LK ZD

The Husqvarna 3/4-16 Hex Top Lock Nut – ZD (Part #: 539110800) is a genuine OEM locking nut designed to provide secure fastening in high-vibration environments. Featuring fine-thread (3/4"-16) and a top-lock design, this nut resists loosening without the need for additional locking hardware. The zinc dichromate (ZD) coating adds corrosion resistance, making it ideal for commercial turf, mower deck, and heavy-duty equipment applications.
