Key Features
- Genuine OEM Fastener Grade — Manufactured to Husqvarna's exact dimensional and material specifications, delivering the thread engagement and clamping force the original design requires.
- Low-Profile Thin Nut Design — The reduced height profile allows installation in space-constrained assemblies where a standard-height nut will not seat correctly.
- Broad Cross-Equipment Compatibility — A single part number covering demolition robots, core drills, wall saws, floor saws, power trowels, and masonry saws across multiple Husqvarna construction equipment families.
- Secure Joint Integrity — Correct thread fit prevents fastener loosening under vibration and load, protecting the integrity of the assembly it secures and avoiding costly secondary damage.
- Verified OEM Part Number — Ordering by part number this part ensures you receive the correct nut profile and thread specification — not a generic substitute that may differ in pitch or hardness grade.
A hexagon thin nut — sometimes called a jam nut or half nut — is a low-profile threaded fastener used to lock a standard nut in place or to secure a component in assemblies where axial space is limited. Its reduced height allows it to fit in locations where a full-height nut would either contact an adjacent part or prevent proper assembly. When this nut is worn, cross-threaded, or missing, the joint it secures can work loose under operational vibration, potentially leading to misalignment or component separation. Using the correct OEM nut ensures the thread form, material hardness, and bearing face dimensions match the original design intent of the assembly.
