The Husqvarna 505551101 J-Bolt.25-20 x 7.25 is a genuine OEM fastener designed for the FS6600DJDT and FS6600DT floor saws. As a direct Husqvarna OEM component, this J-bolt is manufactured to the exact thread specification and dimensional profile required by these machines, ensuring a secure and correctly torqued connection. DHS Equipment supplies this part to help keep your floor saw operating at full capacity with the correct hardware in place.
Key Features
- OEM Thread and Dimensional Accuracy — Manufactured to Husqvarna's exact .25-20 thread pitch and 7.25-inch length specification, delivering the correct clamping force and engagement for structural integrity.
- Genuine Husqvarna OEM Part — Sourced directly from Husqvarna, this fastener meets the same material and hardness standards as the original hardware installed at the factory.
- Direct Drop-In Replacement — Engineered to match the original mounting configuration on the FS6600DJDT and FS6600DT floor saws, fitting existing hardware positions without modification.
- Verified Fitment for FS6600 Series Floor Saws — Confirmed compatibility with the FS6600DJDT and FS6600DT walk-behind flat saws, keeping your machine properly assembled for demanding slab and concrete cutting work.
- Structural Fastener Reliability — A correctly sized and properly torqued J-bolt maintains critical component alignment and prevents loosening under the vibration loads typical of floor saw operation.
A J-bolt is a curved fastener shaped to wrap around or hook through a component, providing a secure anchoring point that resists pull-out and lateral movement. On a walk-behind floor saw like the FS6600DJDT and FS6600DT, J-bolts are used to lock assemblies and guards in position, where consistent clamping tension is essential during heavy-duty concrete cutting. A worn, damaged, or incorrect-size J-bolt can compromise component stability and affect the safe operation of the machine, making correct part number verification — cross-reference 505551101 against your parts diagram — an important step before installation.
