The Husqvarna 593446501 Spring Washer is a genuine OEM component designed for the HTC1500 floor grinder. Sourced directly from Husqvarna, this part matches the original specification for correct load distribution and fastener tension across the assembly it secures. DHS Equipment supplies this part to help keep your equipment running at full capacity.
Key Features
- Genuine OEM Tensioning Spec — manufactured to Husqvarna's exact spring-rate and hardness tolerances, ensuring the washer delivers consistent clamping force without over-compressing or losing preload under vibration.
- Direct Drop-In Replacement — matches the original bore diameter, outside diameter, and seating profile of the HTC1500, so it seats correctly without any reworking of the mating fastener or housing.
- HTC1500 Floor Grinder Compatibility — confirmed fitment for the HTC1500, keeping assembly hardware properly secured during demanding surface-grinding operations.
- Vibration Resistance — the spring-loaded design resists loosening caused by the continuous vibration cycles common in floor grinding, maintaining fastener integrity throughout extended runs.
- Correct Fit Protects Adjacent Components — an undersized or worn washer can allow fasteners to back out, putting stress on surrounding components; using the correct OEM part prevents that chain of damage.
A spring washer sits beneath a fastener head or nut and uses its slight helical or wave profile to maintain consistent clamp load as the assembly experiences vibration and thermal cycling. On a floor grinder like the HTC1500, where the machine generates significant vibration during grinding passes, spring washers are critical to keeping bolted connections tight and preventing fastener migration. When a spring washer loses its temper, flattens, or fractures, the fastener it secures can work loose, leading to misalignment, component wear, or more serious mechanical failure in the assembly it holds together.
