Keep your Husqvarna equipment operating the way it was designed with the Genuine OEM Husqvarna Knob #591344501. Featuring a 5/16-18 thread size and 1″ length, this factory-correct knob provides a secure, tool-free fastening point for panels, guards, and adjustable components — delivering the precise grip and reliable hold your equipment depends on.

Husqvarna OEM knobs are engineered to provide reliable grip and control for various garden and forest machinery, with each part crafted to meet Husqvarna’s exact standards for seamless compatibility and long-lasting performance. The 5/16-18 thread specification is one of the most common fastener sizes across Husqvarna’s line of lawn mowers, lawn tractors, and outdoor power equipment, making this knob a go-to replacement for damaged, cracked, or missing hardware.

This knob features a 4-prong design, providing an ergonomic grip that makes hand-tightening fast and easy — no tools needed for most applications. Whether you’re reassembling a deck panel, securing a guard, or replacing a worn fastener point, this knob threads on cleanly and holds firmly under the vibration and conditions of regular outdoor equipment use.

As a genuine Husqvarna OEM part, #591344501 meets the exact material, thread pitch, and dimensional tolerances Husqvarna specifies — ensuring it seats flush, threads smoothly, and resists stripping or cracking far longer than generic hardware substitutes.
