- Exact Thread and Dimension Match — the M20 thread profile fits the designated stud or shaft position on the FS700E directly, with no rework or adaptation to the mating component
- FS700E Floor Saw Fitment — engineered specifically for the FS700E walk-behind floor saw, keeping the repair straightforward and the parts list accurate
- Maintains Structural Security — a correctly torqued lock nut prevents loosening under the sustained vibration loads generated during concrete and asphalt cutting, protecting the assembly it secures
- Genuine Husqvarna OEM Part — supplied through the authorized parts channel, ensuring the hardware meets the same material and dimensional standards as the original production component
A lock nut is a fastener engineered to resist backing off under vibration, heat cycling, and dynamic load — conditions that floor saws experience continuously during cutting operations. The M20 designation indicates the thread diameter, and using the correct size and grade is critical to maintaining proper clamp load on the assembly it secures. An incorrect or worn lock nut can allow components to shift or work loose, leading to misalignment and potential damage to surrounding parts.
