Key Features
- Genuine OEM Material Grade — sourced directly from Husqvarna, this nut is manufactured to the correct thread specification, hardness, and dimensional tolerance required for secure fastening in demanding construction environments.
- Exact-Match Thread Fit — engineered to the original thread pitch and dimensional profile, this fastener seats and torques correctly without rework or adjustment.
- Broad Husqvarna Fitment — compatible with the FS400LV and FS600E floor saws as well as the PG680, PG680RC, PG820, and PG820RC floor grinders, covering a wide range of Husqvarna Construction equipment.
- Structural Connection Integrity — a correctly fitted nut maintains the clamping force and alignment of assembled components; a worn, stripped, or incorrect fastener can allow movement, vibration-induced loosening, or component damage during operation.
A nut is a threaded fastener that works in conjunction with a bolt or stud to clamp and secure components firmly in place. In floor saws and floor grinders, fasteners like this one hold assemblies together under sustained vibration, cutting loads, and operational stress. When a nut becomes stripped, corroded, or lost, the integrity of the entire assembly it secures is compromised — making an exact OEM replacement essential for restoring the machine to safe, stable working condition.
